RF & Wireless Products

RF & Wireless Products New BAW Filters Provide Greater Power Handling and High Rejection for Infrastructure Applications Technical Details: New DRO Series VCOs with Electrical Tuning 8 to 12 GHz Z-Communications, Inc., the leader in Voltage Controlled Oscillator (VCO) technology, has raised performance standards to new heights through the introduction of the DRO Series of high performance oscillators. DRO oscillators are sure to meet the demands of any Up/Down Converter system requiring an ultra-low phase noise LO solution. The DRO Series of high frequency oscillators use high-Q dielectric resonators and are currently available at 8 to 12 GHz. The electrical tuning option for the DRO operating at 10 GHz has a control range of 0-12 Vdc, providing ultra-fine tuning precision. The electrical tuning provides ±3 MHz of frequency control allowing the oscillator to be quickly and easily phase-locked. DRO Series oscillators provide a low phase noise and an exceptional spectral purity as good as -110 dBc/Hz, typically, at 10 kHz from the carrier. DROs minimize power consumption by operating off a 5 Vdc bias while drawing only 20 mA, typically, and are available in a surface mount packages measuring 0.91 x 0.91 x 0.40 inches. For rugged applications, DROs are available in a connectorized metal enclosure measuring 1.25 x 1.25 x 0.85 inches. In addition to the superior phase noise performance and electrical tuning advantage, the DRO series oscillators deliver 0 ± 3 dBm of output power into a 50 ohm load. DROs are designed to operate over the industrial temperature range of -40 to 85°C making them a good fit for the toughest environmental applications. These exceptional devices will enhance any PLL control system due to their low tuning sensitivity figure of approximately 1 MHz/V. The DRO Series oscillators have second harmonic attenuation of better than -25 dBc. The pushing specification for the 10 GHz DRO is less than 1 MHz/V within a 5% change of the supply voltage while pulling is less than 2 MHz with a 12 dB return loss, any phase. ■ Z-Communications www.zcomm.com TriQuint Semiconductor, Inc. has released three new bulk acoustic wave (BAW) RF bandpass filters that can handle more power while providing greater temperature stability and superior signal rejection for high performance infrastructure applications. TriQuint’s new filter solutions fully exploit the benefits of BAW technology, which is superior to other products available for these applications. TriQuint BAWs provide greater temperature stability at microwave frequencies in addition to a compact footprint. They are well suited for use in base stations, repeaters, distributed antenna systems, tower-mounted amplifiers and many other wireless applications. All three BAW filters have narrow transition bandwidths between their passbands and stopbands for better signal rejection, and do not need external 50 Ohm matching circuits. • 885024: Band 2 BAW RF bandpass filter: 1960 MHz center frequency; 1930 - 1990 MHz passband; +33 dBm RF power handling; 20 dB rejection at 1920 MHz; 5.5 dB maximum insertion loss. Offered in a 3x3 mm hermetic ceramic package. • 885025 Band 2 BAW RF bandpass filter: 1880 MHz center frequency, 1850 -1910 MHz passband; +30 dBm RF power handling; 20 dB rejection at 1920 MHz, 5.5 dB maximum insertion loss. Offered in a 3x3 mm hermetic ceramic package. • 885009 Band 7 BAW RF bandpass filter: 2535 MHz center frequency, 2500 - 2570 MHz passband; +30 dBm RF power handling; 30 dB rejection at 2170 MHz, 3.5 dB maximum insertion loss. Offered in a 3x3 mm hermetic ceramic package. TriQuint’s new BAW bandpass filters are in production; samples and evaluation fixtures are available. ■ TriQuint www.tqs.com New 4812 MHz Coaxial Resonator Oscillator (CRO) Crystek’s new CVCO55CXT-4812-4812 Coaxial Resonator Oscillator (CRO) is a coaxial-based VCO with an internal proprietary frequency doubler. The CVCO55CXT family’s frequency doubling, 2X fundamental technology reaches new performance levels of lower phase noise and much lower harmonics over the competition, while achieving lower current consumption in the process. The CVCO55CXT-4812-4812 operates at 4812 MHz with a tuning voltage range of 0.3 Vdc to 4.7 Vdc. This coaxial VCO features a typical phase noise of -102 dBc/ Hz @ 10 kHz offset and has good linearity. The CVCO55CXT-4812-4812 CRO exhibits an output power of 3.0 dBm typ. into a 50 ohm load with a supply of +5.0 Vdc and a current consumption of 25 mA (max.). Engineered and manufactured in the USA, the CVCO55CXT-4812-4812 CRO is packaged in the industry-standard 0.5-in x 0.5-in package. Pushing and Pulling are both minimized to 1.5 MHz/V and 0.5 MHz, respectively. Second harmonic suppression is -30 dBc typical. The CVCO55CXT-4812-4812 is ideal for use in applications such as digital radio equipment, fixed wireless access, satellite communications systems, and base stations. ■ Crystek Corporation. www.crystek.com 50 hf-praxis 4/2013

RF & Wireless Frequency Planning Wizard for Determining Spurious Free Bandwidths in Communication System Design AWR Corporation announced RFP, an innovative new frequency planning wizard within Visual System Simulator (VSS) that enables engineers to effortlessly and efficiently determine spurious free bandwidths when designing complex radio communications systems. Whether developing satellite communication, cellular, or military radio links, RFP is an essential part of the design process in that it provides greater insight into unwanted signals or spurs generated in a specified bandwidth. As well as analyzing spurs generated by a lineup of mixers, RFP analyzes the entire RF lineup of common components (amplifiers, mixers, filters, etc.) found in radio communication links. RFP excels as a frequency planning simulation tool in two ways. First, in addition to spur analysis, RFP gives engineers the first cut of cascaded measurements such as noise figure (NF), gain compression (P1dB), signal-to-noise-ratio (SNR) and third-order intermodulation (IM3), as well as spurious free dynamic range. Second, RFP is seamlessly integrated with AWR’s VSS communications system design software so that with a single mouse click the RF link constructed in RFP is automatically translated to a VSS system diagram. VSS can then be used to account for mismatch between components, account for noise at image frequency, and run yield analysis and optimization. Engineers then have a choice of modulated signals and can perform, for example, error vector magnitude (EVM), adjacent channel power ratio (ACPR), and bit error rate (BER) measurements. RFP is available now as an add-on, cost-option module to VSS. ■ AWR www.awrcorp.com New DOCXO from Bliley WiFi Front End Modules RFMD‘s new RFFM8xxx series provide complete integrated solutions in single front end modules (FEMs) for WiFi systems. The ultra-small form factor and integrated matching minimizes the layout area in the customer‘s application and greatly reduces the number of external components.

Developed for critical applications where exceptional Frequency vs. Temperature performance is required, the N6B series stability is rated at ±0.4ppb over an operating temperature range of -20 to +70 degrees Celsius. Two variations of the N6B series, the N6B-ABA-D1A-10M and N6B- ABA-D1B-10M, provide a sine wave output of +5 dBm (typ.) into 50 ohms. Bliley‘s N6B series DOCXO operate from a +5 VDC supply with or without Electronic Frequency Control and offer aging performance per year of less than ±0.1ppm. Phase noise at 10 kHz offset is -150 dBc/Hz. With an attractive performance vs. price ratio, the N6B series is well suited for network timing and general precision applications where exceptional stability is required. The N6B series DOCXO are housed in a standard Double Oven through-hole package measuring 36.2 mm (L) x 27.3 mm (W) x 23.8 mm (H).
