HMC375LP3 / 375LP3E
v03.0610 AMPLIFIERS -LOW NOISE -SMT 7 GaAs PHEMT MMIC LOW NOISE
AMPLIFIER, 1.7 -2.2 GHz Typical Applications Features The HMC375LP3 / HMC375LP3E is ideal for
basestation receivers: Noise Figure: 0.9 dB • GSM, GPRS & EDGE Gain: 17 dB • CDMA & W-CDMA Very Stable Gain vs. Supply & Temperature • DECT Single Supply: +5V @ 136 mA Output IP3: +34 dBm 50 Ohm Matched Output Functional Diagram General Description
The HMC375LP3 & HMC375LP3E high dynamic
range GaAs PHEMT MMIC Low Noise Amplifiers are
ideal for GSM & CDMA cellular basestation front-end
receivers operating between 1.7 and 2.2 GHz. This
LNA has been optimized to provide 0.9 dB noise
figure, 17 dB gain and +33 dBm output IP3 from
a single supply of +5V @ 136mA. Input and output
return losses are 14 dB typical with the LNA requiring
minimal external components to optimize the RF input
match, RF ground and DC bias. For applications
which require improved noise figure, please see the
HMC618LP3(E). Electrical Specifi cations, TA = +25° C, Vs = +5V
