RF & Wireless Components

RF & Wireless Components Products PIN Diode Switches Covering Frequencies from 10 MHz to 67 GHz Pasternack greatly expands their portfolio of in-stock solid state PIN diode switches covering frequencies from 10 MHz to 67 GHz. 69 unique new models of 50 ohm PIN diode switches are available in compact connectorized package styles and display impressive isolation, insertion loss, and switching speed performance. News 5G Ready & Millimeter Wave Supplement Catalog Announcement Pasternack’s new PIN diode switches offer a broad range of solutions in applications where fast switching and long lifetime are critical. These PIN diode switches are used extensively in aerospace, defense, and commercial RF, microwave, and millimeter-wave communication systems, switch matrix assemblies, and production testing environments for a variety of signal routing functions between control components. Integrated TTL-compatible driver circuitry offers accurate logic controls for computer command and automated test systems. The PIN diode switches from Pasternack are available in popular configurations including SPST, SPDT, SP3T, SP4T, SP5T, SP6T, SP8T, SP12T, and Transfer models that cover select broadband frequencies ranging from 10 MHz to 67 GHz. These switches offer superior performance with high isolation up to 80 dB, fast switching speeds down to 50 nsec, insertion loss levels as low as 1 dB, and dual operating voltage ranges from -15 to -5 and +5 Vdc. Maximum RF input power handling varies from 0.1 to 1 watt (CW) depending on the model. Additionally, all models are available in rugged packages that are designed to meet military grade environmental test conditions and several models feature field replaceable connectors. ■ Pasternack www.pasternack.com MECA (Microwave Equipment & Components of America) announced the Millimeter Wave Supplement (Issue 2) publication. Including the latest 5G ready components operating up to 40 GHz. Since 1961 MECA Electronics has served the RF/Microwave industry with equipment and passive components covering Hz to 40 GHz. MECA is a ISO9001:2008 certified global designer and manufacturer for the communications industry with products manufactured in the United States of America offers a 36-month warranty. ■ MECA Electronics Inc. www.e-meca.com GaN Power Amplifier Operating in the 2 to 6 GHz Band Pasternack announced their new PE15A5025 50 Watt gallium nitride (GaN) coaxial power amplifier operating in the popular 2 to 6 GHz frequency band. The compact and rugged design delivers high levels of output power and efficiency and has the advantage of high output load impedance that makes port matching easier over wider bandwidths using lower loss components. Applications for the PE15A5025 amplifier include commercial and military radar, jamming systems, medical imaging, wireless communications and electronic warfare. This GaN power amplifier from Pasternack offers 50 dB of small signal gain with a saturated output power level of 47 dBm typical and 30% power added efficiency (PAE). While generating 50 watts of saturated output power under worst case conditions, the output harmonic response is -15 dBc and spurious levels are kept at -70 dBc. The amplifier requires a 28 V dc power supply and is unconditionally stable. Other desired features include integrated voltage regulation, bias sequencing circuitry, DC control TTL logic, DC current monitoring, and over temperature shutdown at 90 °C baseplate temperature for added reliability. The PE15A5025 amplifier uses female SMA input/output RF connectors and a 15 Pin Micro- D Female socket is used for DC, TTL blanking, and over current and temperature monitoring. The assembly operates over the temperature range of -40 and +85 °C and the rugged package is designed to withstand harsh military standard environmental test conditions that include humidity, altitude, shock and vibration. An external heatsink with fan for cooling (see PE15A5990) is recommended for this model. ■ Pasternack www.pasternack.com 72 hf-praxis 7/2016

RF & Wireless Products DC Blocking Power Dividers applications including FM and VHF TV broadcast, industrial, scientific and medical RF power generators. It is suitable for any RF power application in the 10 to 600 MHz range. High-Frequency 50 Ohm Coaxial Terminations Low-PIM In-Line Reactive Splitters MECA offers a full line of DC blocking power dividers. Ideal for GPS, In-building, 5G and backhaul upgrade applications. Available in 2, 3, 4, 6, 8, 12 & 16 way configurations in N, SMA, BNC & TNC connector styles covering 800 MHz to 2.2 GHz with expanded models coming soon covering 698 MHz to 2.7 GHz. Made in USA and 36-month warranty. ■ MECA Electronics Inc. www.e-meca.com 1400 CW Extremely Rugged Reliable RF Transistor Withstands High VSWR The device also has a number of parameters that contribute to it offering excellent reliability characteristics for the end application. These include a higher BVDSS breakdown voltage, improved parasitic bipolar breakdown, and an improved Class C operation due to a new ESD-diode structure that has a larger negative voltage range. Also, the device offers good stability and spurious behaviour at a VSWR 90:1. The BLCU188XRS is currently sampling with general availability due in Q3, 2016. ■ Ampleon Netherlands B.V www.ampleon.com Multiplexers in Two, Three or Four Channel Versions RLC Electronics‘ high-frequency 50 ohm coaxial terminations provide low VSWR over a frequency range of DC to 40 GHz (2.92 mm termination). These compact units utilize precisely matched resistors, resulting in a VSWR of less than 1.2:1. These terminations can handle up to 2 watts at 40 GHz. ■ RLC Electronics Inc. www.rlcelectronics.com New Low-PIM Switches MECA’s Low-PIM (-160 dBc typ.) reactive splitters for DAS applications, with rugged construction and excellent performance across all wireless bands from 0.698 to 2.7 GHz make them ideal for in-building or tower top systems.

The BLCU188XRS has unmatched input and output making it suitable for a wide variety of RLC Electronics‘ Multiplexers are available in two, three or four channel versions. Adjacent passbands may be designed for a contiguous or non-contiguous response. For passband frequencies below 2 GHz, lumped element designs will often achieve the desired response in the smallest package. At higher frequencies (up to 40 GHz), distributed coaxial structures are employed to realize the lowest possible loss. RLC Electronics can supply Multiplexers for most applications, including commercial, telecommunications, and military specifications. ■ RLC Electronics Inc. www.rlcelectronics.com RLC Electronics is proud to introduce a series of low-PIM switches, with offerings from SP2T to SP12T. These Switches are available in any frequency range from DC up to 65 GHz, and the low PIM designs offer the customer the ability to reduce intermodulation in active devices in order to reduce system interference. Typical performance ranges from -160 to -175 dBc, and the high isolation minimizes cross-talk between channels to ensure signal integrity. Customer applications include DAS, surveillance and communication systems. Low passive intermodulation is crucial for applications where two or more transmitted signals share a common antenna or whenever the transmitter signal is too high or the receiver is sensitive to high intermodulation. ■ RLC Electronics, Inc. www.rlcelectronics.com Microwave/L-Band 2-Way & 4-Way Power Dividers MECA expands its extensive stripline power divider line to include L-Band 2-way and 4-way Wilkinson power dividers which are optimized for excellent performance covering 1 to 2 GHz, 2-way (802-2-1.500- M01) and 4-way (804-2-1.500- M02) with minimum isolation of 20 dB, 0.3 dB max. insertion loss and amplitude balance of 0.3 dB max.
