HMC463LH250
v06.1217 AMPLIFIERS -LOW NOISE -SMT GaAs pHEMT MMIC LOW NOISE
AGC AMPLIFIER, 2 -20 GHz
Typical Applications Features The HMC463LH250 is ideal for: 50 Ohm Matched Input/Output • Telecom Infrastructure Hermetic SMT Package • Microwave Radio & VSAT Gain: 14 dB • Military EW, ECM & C I Noise Figure: 2.5 dB @ Mid-Band • Test Instrumentation P1dB Output Power: +18 dBm @ Mid-Band • Fiber Optics Supply Voltage: +5V @ 60mA 3 Screening to MIL-PRF-38535 (Class B or S) Available Functional Diagram General Description
The HMC463LH250 is a GaAs MMIC pHEMT Low
Noise AGC Distributed Amplifier packaged in a
hermetic surface mount package which operates
between 2 and 20 GHz. The amplifier provides 13
dB of gain, 3 dB noise figure and 18 dBm of output
power at 1 dB gain compression while requiring only
60 mA from a +5V supply. An optional gate bias
(Vgg2) is provided to allow Adjustable Gain Control
(AGC) of 8 dB typical. Gain flatness is excellent at
±0.5 dB from 2 -14 GHz making the HMC463LH250
ideal for EW, ECM RADAR, test equipment and
High-Reliability applications. The HMC463LH250
LNA I/Os are internally matched to 50 Ohms and are
internally DC blocked. Electrical Specifications, TA = +25° C, Vdd= 5V, Vgg2= Open, Idd= 60 mA*
