Features
High P1dB Output Power: +31 dBm
High Psat Output Power: +33 dBm
High Gain: 12 dB
High Output IP3: +41 dBm
Supply Voltage: Vdd = +10V to +15V @ 500 mA
50 Ohm Matched Input/Output
Die Size: 2.99 x 1.84 x 0.1 mm
General Description
The HMC998A is a GaAs MMIC PHEMT Distributed
Power Amplifier die which operates between 0.1
and 22 GHz. The amplifier provides 12 dB of gain,
+41 dBm output IP3 and +31 dBm of output power at
1 dB gain compression while requiring 500 mA from
a +15V supply. This versatile PA exhibits a positive
gain slope from 1 to 18 GHz making it ideal for EW,
ECM, Radar and test equipment applications. The
HMC998A amplifier I/Os are internally matched
to 50 Ohms facilitating integration into mutli-chip-
modules (MCMs). All data is taken with the chip
connected via two 0.025mm (1 mil) wire bonds of
minimal length 0.31 mm (12 mils).
