GPS LNA Diplexer
This LNA/diplexer assembly designed for use in Global Positioning System (GPS) applications features a 1.8 dB (typ) noise figure for both the L1 and L2 channels. Typical gain is 55 dB and third-order intercept point (IP3) is +30 dBm. Additional features include an input limiter for protection from signals as high as 400 W pulsed and 1 W CW.
Multiband Power Amplifiers
These multiband, 250 W power amplifiers offer an alternative source of variable RF power for more efficient electromagnetic interference (EMI)/electromagnetic compatibility (EMC) applications in the 1 to 18 GHz frequency range. The units feature multistage collector traveling-wave tubes, making them more efficient and less expensive. In addition, the units feature advanced SWR protection circuitry and comply with all standard international safety and EMC requirements.

Wireless Low Noise Amplifier
The model PA1109 amplifier offers an IP3 of 49 dBm, output power of 33 dBm and low noise figure of 2 dB. The unit can be used in the receive path and as a driver to the transmit stage.
Phoenix Microwave Corp.,
6 W CDMA Transistor
The model SM1820-43 CDMA FET operates from 1850 to 1990 MHz with a 1 dB compression point of 20 W and can deliver 6 W CDMA with 45 dB of linear gain. The small GaAs FET module operates from +12 V and consumes 6.5 A quiescent. Standard features include gain control of less than 20 dB, over-/reverse-voltage protection, logic on/off and thermal protection with auto reset. Available options include forward/reverse power detection and harmonic filtering. Delivery: stock to four weeks (ARO).
