HMC637A
v01.0715 AMPLIFIERS -LINEAR & POWER -CHIP GaAs MMIC 1 WATT
POWER AMPLIFIER DC -6 GHz
Typical Applications Features The HMC637A is ideal for: P1dB Output Power: +30.5 dBm • Telecom Infrastructure Gain: 14 dB • Microwave Radio & VSAT Output IP3: +41 dBm • Military & Space Bias Supplies: +12V, +6V, -1V • Test Instrumentation 50 Ohm Matched Input/Output • Fiber Optics Die Size: 2.98 x 2.48 x 0.1 mm Functional Diagram General Description
The HMC637A is a GaAs MMIC MESFET Distributed
Power Amplifier die which operates between DC and
6 GHz. The amplifier provides 14 dB of gain,
+41 dBm output IP3 and +30.5 dBm of output power
at 1 dB gain compression while requiring 400mA
from a +12V supply. Gain flatness is excellent at ±0.5
dB from DC to 6 GHz making the HMC637A ideal for
EW, ECM, Radar and test equipment applications.
The HMC637A amplifier I/Os are internally matched
to 50 Ohms facilitating integration into Mutli-ChipModules (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). Electrical Specifications, TA = +25° C, Vdd= +12V, Vgg2= +6V, Idd= 400mA[1]
