General Description
The HMC461LP3 & HMC461LP3E are 1.7 - 2.2 GHz
high output IP3 GaAs InGaP Heterojunction Bipolar
Transistor (HBT) dual-channel MMIC amplifiers.
The linear performance of two HMC455LP3 high
IP3 drivers is offered in this single IC which can be
configured in a balanced or push-pull amplifier circuit.
The amplifier provides 12 dB of gain and +30.5 dBm
of saturated power at 48% PAE from a single +5 Vdc
supply while utilizing external baluns in a balanced
configuration. The high output IP3 of +45 dBm coupled
with the low VSWR of 1.2:1 make the HMC461LP3
& HMC461LP3E ideal driver amplifiers for PCS/3G
wireless infrastructures. A low cost, leadless 3x3 mm
QFN surface mount package (LP3) houses the dual
MMIC amplifier IC. The LP3 provides an exposed
base for excellent RF and thermal performance.
