HMC372LP3 / 372LP3E
GaAs PHEMT MMIC LOW NOISE
AMPLIFIER, 700 - 1000 MHz
v03.0610
General Description
Features
Functional Diagram
The HMC372LP3 & HMC372LP3E are GaAs PHEMT
MMIC Low Noise Ampli ers that are ideal for GSM
& CDMA cellular basestation front-end receivers
operating between 700 and 1000 MHz. The ampli er
has been optimized to provide 1 dB noise gure, 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 gure, please see the
HMC617LP3(E).
Noise Figure: < 1 dB

ACG
AC Ground - An external capacitor of 0.01μF to
ground is required for low frequency bypassing.
See Application Circuit for further details.
Vdd Power supply voltage. Choke inductor and bypass
capacitor are required. See application circuit.

Evaluation PCB
The circuit board used in the application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package ground
leads and exposed paddle should be connected
directly to the ground plane similar to that shown.
A sufficient number of via holes should be used to
connect the top and bottom ground planes. The
evaluation circuit board shown is available from
Hittite upon request.
