Typical Applications Features The HMC994A is ideal for: High P1dB Output Power: 28 dBm • Test Instrumentation High Psat Output Power: 30 dBm • Military & Space High Gain: 14 dB • Fiber Optics High Output IP3: 39 dBm
Supply Voltage: +10 V @ 250 mA
50 Ohm Matched Input/Output
Die Size: 2.75 x 1.45 x 0.1 mm Functional Diagram General Description
The HMC994A is a GaAs MMIC pHEMT Distributed Power Amplifier which operates between DC
and 30 GHz. The amplifier provides 14 dB of gain,
+39 dBm output IP3 and +28 dBm of output power at
1 dB gain compression while requiring 250 mA from
a +10 V supply. The HMC994A exhibits a slightly
positive gain slope from 2 to 20 GHz, making it ideal
for EW, ECM, Radar and test equipment applications. With up to 39 dBm Output IP3 the HMC994A
is ideal for high linearity applications in military and
space as well as test equipment where high order
modulations are used. The HMC994A amplifier I/Os
are internally matched to 50 Ohms facilitating integration into Multi-Chip-Modules (MCMs). All data
is taken with the chip connected via two 0.025 mm
(1 mil) wire bonds of minimal length 0.31 mm (12 mils). Electrical Specifications, TA = +25° C, Vdd = +10 V, Vgg2 = +3.5 V, Idd = 250 mA*
