Two New High Linearity VGAs are Ideal for Microwave Radio

The HMC996LP4E and the HMC997LC4 are GaAs PHEMT MMIC analog variable gain amplifiers which operate from 5 to 12 GHz and from 17 to 27 GHz respectively. Across the line, these versatile amplifiers delivers up to 20.5 dB of gain, +24 dBm, of output P1dB, and +34 dBm of output IP3 in their maximum gain state. Each of these amplifiers is controlled by a single analog control voltage between 0 and -4.5V, and provides up to 22 dB of gain control range. The high linearity performance of the HMC996LP4E and the HMC997LC4 allows them to be used as either buffer amplifiers, or as power amplifier pre-drivers in microwave transmitter applications.

The HMC996LP4E consumes 120 mA from a +5V supply, and is housed in a RoHS compliant 4 x 4 mm QFN leadless package. The HMC997LC4 consumes only 170 mA from a +5V supply, is housed in a RoHS compliant 4 x 4 mm ceramic QFN leadless package. The HMC996LP4E and the HMC997LC4 are compatible with high volume surface mount manufacturing, and both feature excellent gain flatness making them well suited for military EW, ECM and radar applications.
