HMC372LP3 / 372LP3E
v03.0610 AMPLIFIERS -LOW NOISE -SMT 7 GaAs PHEMT MMIC LOW NOISE
AMPLIFIER, 700 -1000 MHz Typical Applications Features The HMC372LP3 / HMC372LP3E is ideal for
basestation receivers: Noise Figure: < 1 dB • GSM, GPRS & EDGE Gain: 15 dB • CDMA & W-CDMA Very Stable Gain vs. Supply & Temperature • Private Land Mobile Radio Single Supply: +5V @ 100 mA Output IP3: +34 dBm 50 Ohm Matched Output Functional Diagram General Description
The HMC372LP3 & HMC372LP3E are GaAs PHEMT
MMIC Low Noise Amplifiers that are ideal for GSM
& CDMA cellular basestation front-end receivers
operating between 700 and 1000 MHz. The amplifier
has been optimized to provide 1 dB noise figure, 15
dB gain and +34 dBm output IP3 from a single supply
of +5V @ 100 mA. Input and output return losses are
25 and 14 dB respectively with the LNA requiring only
four external components to optimize the RF Input
match, RF ground and DC bias. For applications
which require improved noise figure, please see the
HMC617LP3(E). Electrical Specifi cations, TA = +25° C, Vs = +5V
