Product Details

The HMC694 is a GaAs MMIC PHEMT analog variable gain amplifier die which operates between 6 and 17 GHz. Ideal for microwave radio applications, the amplifier provides up to 24 dB of gain, output P1dB of up to 22 dBm, and up to 30 dBm of Output IP3 at maximum gain, while requiring only 170 mA from a +5V supply. A gate bias (Vctrl) is provided to allow variable gain control up to 23 dB. Gain flatness is excellent from 6 to 17 GHz, making the HMC694 ideal for EW, ECM and radar applications.

The HMC694 can easily be integrated into Multi-Chip-Modules (MCMs) due to its small size and no external matching. All data is taken with the chip in a 50 Ohm test fixture connected via 0.025 mm (1 mil) diameter wire bond of minimal length 0.31 mm (12 mils).
