Functional Diagram
General Description
The HMC373LP3 is a versatile, high dynamic range
GaAs MMIC Low Noise Ampli鏗乪r that integrates a
low loss LNA bypass mode on the IC. The ampli鏗乪r
is ideal for GSM & CDMA cellular basestation front-
end receivers operating between 700 and 1000
MHz and provides 0.9 dB noise 鏗乬ure, 14 dB of gain
and +35 dBm IP3 from a single supply of +5.0V @
90 mA. Input and output return losses are 28 and
12 dB respectively with the LNA requiring minimal
external components to optimize the RF input
match, RF ground and DC bias. By presenting an
open or short circuit to a single control line, the LNA
can be switched into a low 2.0 dB loss bypass mode
reducing the current consumption to 10 碌A(chǔ). A low
cost, leadless 3x3 mm QFN surface mount package
(LP3) houses the low noise ampli鏗乪r.
