RF & Wireless Microwave

RF & Wireless Microwave Components USB Controlled Microwave and Millimeter Wave Components Pasternack releases their brand new lines of USB controlled microwave and millimeter wave components which includes amplifiers, attenuators and PIN diode switches. The new components from Pasternack are controlled and powered by a convenient USB 2.0 port with driverless installation, meaning no external power supply is required. The attenuators and PIN diode switches require an easy-touse downloadable software program which interfaces with any Windows computer. The company is releasing two models each of the amplifiers, switches and attenuators that cover extremely wide frequency bands up to 40 GHz. The modules are 50 Ohm hybrid MIC designs that do not require any external matching components. Pasternack’s new USB controlled amplifiers offer typical performance of 12 dB gain, 10 dBm P1dB, a 4.5 dB noise figure and operate over a 50 MHz to 18 GHz band or 50 MHz to 40 GHz band. The attenuators offer typical performance of 30 dB attenuation, 5 to 8 dB of insertion loss, a 1 dB step size and are available in two programmable models that cover 100 MHz to 18 GHz and 100 MHz to 40 GHz. Lastly, the SPDT switches offer typical performance 3 to 5 dB of insertion loss, 65 to 70 dB isolation, a 6 µsec switching speed and are available in two models that cover 500 MHz to 18 GHz and 500 MHz to 40 GHz. All models operate over a broad temperature range of -40 to +85 °C and depending on the frequency, are available with either female SMA or 2.92 mm connectors. ■ Pasternack www.pasternack.com Components 2 Watt Amplifier with Integrated Power Detector M/A-COM announced the new MAAP- 011145, a power amplifier designed specifically for 18 GHz wireless backhaul applications. The MAAP-011145 is a power amplifier covering the 17.6...19.75 GHz frequency band in a 7 mm, lead-free, cavity package. This device features a temperature compensated integrated power detector, and includes ESD protection and by-pass capacitors to ease the implementation and volume assembly of the packaged part. The MAAP-011145 boasts over 2 watts output power at 1 dB compression point, 25 dB small signal gain, a OIP3 of 43 dBm and a noise figure of 7 dB and 34.5 dBm of saturated output power. The MAAP-011145 provides customers with a robust, high performance solution for demanding cellular backhaul applications. ■ M/A-COM Technology Solutions Holdings, Inc. www.macom.com 140 W ISM Band Transistor Provides Clean Power RFMW, Ltd. announced design and sales support for an LDMOS power transistor internally matched for broadband operation from 2.4 to 2.5 GHz. NXP’s BLF- 2425M7LS140 provides 140 W average CW power with 18.5 dB of gain. The BLF- 2425M7LS140 draws 1.3 A from a 28 V supply with efficiencies up to 52%. Housed in a ceramic package with solder ears, the BLF2425M7LS140 is a highly rugged transistor for industrial heating applications. NXP provides a range of high power transistors for the industrial, scientific and medical (ISM) band centered at 2450 MHz. NXP solid state RF amplifiers enable highly reliable, more efficient and more controllable clean power sources for RF plasma, industrial drying and cooking when compared to alternatives such as magnetrons. ■ NXP Semiconductor RFMW, Ltd. info@rfmw.com 5 W GaN PA Performs from 2 to 18 GHz RFMW, Ltd. announces design and sales support for a two-stage wideband power amplifier supporting Test Instrumentation, EW and Radar applications from 2 to 18 GHz. The Qorvo TGA2214 provides 5 watts of saturated output power with a large signal gain of >14 dB. Small signal gain is >22 dB Biased from a 22 V supply, the Qorvo TGA2214 draws 450 mA of current. PAE measures greater than 20%. Qorvo offers the TGA2214 as a 3x5 mm DIE. ■ Qorvo Stocking Distributor RFMW, Ltd. info@rfmw.com 100 W Iso-Attenuator Protects and Monitors RFMW, Ltd. announced design and sales support for the Iso-Attenuator model RFSL2536-A30 from RF Circulator Isolator, Inc. (RFCI). RFCI Iso-Attenuators protect active components from distortion or potentially damaging reflected power while providing a convenient, attenuated port for monitoring RF power. As part of a feedback loop, the 30 dB attenuated signal allows RF power to be regula- 50 hf-praxis 7/2015

RF & Wireless elspec GmbH Components ted. The RFSL2536-A30 is capable of handling 1 kW peak / 200 W average forward power and 100 W CW reverse power into the on-board, 30 dB attenuator. Spanning 1920 to 2125 MHz, the RFCI RFSL2536- A30 provides >23 dB typical port-to-port isolation while maximum insertion loss is 0.25 dB. Offered in a 25.4x19x8 mm dropin, tabbed package, the RFSL2536-A30 is a robust alternative to individual isolator/ directional coupler designs. ■ Radio Frequency Circulator Isolator, Inc. (RFCI ) RFMW, Ltd. info@rfmw.com New Log Video Amplifiers with Broadband Performance Up to 18 GHz Pasternack introduces an all new line of broadband log video amplifiers covering multi-octave bandwidths from 0.5 GHz to 18 GHz. The 5 models being released include 4 Successive Detection Log Video Amplifiers (SDLVA), and 1 Detector Log Video Amplifier (DLVA), which offer a wide input dynamic range, high signal sensitivity, fast recovery times, and excellent temperature stability. Pasternack’s log amplifiers are used to measure widely varying signals at high frequencies in applications where rapid and precise tracking is required across the entire frequency band. Signals with high density pulses, narrow pulse widths and large amplitude variations are compressed into an output video voltage response that increases linearly with increasing input power. Common applications for these RF amplifies are in radar and EW systems used for direction finding and power monitoring, in laboratory measurement and test equipment and in telecommunications and data communications systems. The new logarithmic video amplifiers from Pasternack utilize GaAs semiconductor technology which is beneficial for high speed applications while maintaining flatness and accuracy throughout the desired frequency band. These log amplifiers can process up to 75 dB of dynamic range and have log linearity that ranges from ±1 to ±2.5 dBm. The log slope ranges from 20 to 50 mV/dB and they also boast fast recovery times ranging from 40 to 150 nanoseconds. The 50 ohm hybrid circuit assemblies are enclosed in rugged metal packages with SMA connectors. They are highly reliable and designed to meet MIL-STD-202F environmental conditions. ■ Pasternack www.pasternack.com Highly Integrated Front-end Module for Mobile Platforms Für jede Anforderung das optimale Produkt zum besten Preis. elspec distribute: Standardartikel sofort „as is“ bestellen elspec customize: Sonderartikel Sondermaße Konfektionen elspec manufactory: Speziallösungen mit großem Know-how in aufwändiger Handarbeit gefertigt Skyworks introduces a highly integrated, 5 GHz 802.11ac/n front-end module for mobile platforms including smartphones and tablets.
