HMC694
v03.1108 GaAs MMIC ANALOG VARIABLE
GAIN AMPLIFIER, 6 -17 GHz Typical Applications Features The HMC694 is ideal for: Wide Gain Control Range: 23 dB • Point-to-Point Radio Single Control Voltage • Point-to-Multi-Point Radio Output IP3 @ Max Gain: +30 dBm • EW & ECM Output P1dB: +22 dBm
No External Matching • X-Band Radar Die Size: 2.26 x 0.97 x 0.1 mm • Test Equipment General Description Functional Diagram 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
bonds of minimal length 0.31 mm (12 mils). Variable gain amplifiers -CHIP 6 Electrical Specifications, TA = +25° C, Vdd1, 2, 3= 5V, Vctrl= -2V, Idd= 170 mA*
