PMI Model P4T-0R1G20G-100-T-SFF is a single pole, four throw, solid-tate absorptive switch that operates over the 100 MHz to 20 GHz frequency range. This model provides 110 dB of isolation over the entire frequency range of operation and offers low insertion loss performance with fast switching speeds.

PMI Model ERDLVA-218-CW-LPD is a CW Immune, Extended Range Detector Logarithmic Video Amplifier (ERDLVA) designed for ultra low DC power consumption. This model operates over the 2 to 18 GHz frequency range and has the ability to interface with an output cable measuring over 100 feet in length.

Hittite Microwave Corp., the world class supplier of complete MMIC based solutions for communication & military markets, announces the release of two new SMT packaged GaAs MMIC variable gain amplifiers (VGAs) which are ideal for VSAT, microwave radio, military, and test & measurement equipment applications from 5 to 27 GHz.

Designed specifically for WiMAX Base station, Renaissance Electronics’ 15C2NM is the RF interface DAS panel that duplexes the BTS port for Rx/UL and Tx/DL channels with the help of a circulator. The power levels on the UL and DL can be adjusted by the use of fixed and manual rotary attenuators.

Renaissance has designed a new octave band drop-in circulator, 3G7BH that covers a bandwidth of 5.2 to 11 GHz over -20 ° to +85° C. With insertion loss less than 0.95 dB over the entire band, the circulator is robust to handle 20 W of incident RF power. Return loss and isolation of 13 dB ensures better match to the RF circuitry where it's being placed.

This 4-Way Combiner operates from 20-1000 MHz at 100 W CW, measured at the sum port. This small package enables our customers to combine four 25 W modules in a harsh military environment, often operating into other than 50 Ω.

The Werlatone 90° Hybrid Coupler, Model QH8600, is the first 4-Port, stripline design, covering the full 30-520 MHz bandwidth. This fully bonded; stripline unit is designed for amplifiers and radios in the VHF/UHF band. Conservatively rated at 250 W CW, this unit eliminates ferrites and will withstand severe input unbalances
