HMC385LP4 / 385LP4E
MMIC VCO w/ BUFFER
AMPLIFIER, 2.25 - 2.5 GHz
Features
Pout: +4.5 dBm
Phase Noise: -115 dBc/Hz @100 KHz
No External Resonator Needed
Single Supply: 3V @ 35 mA
QFN Leadless SMT Package, 16 mm2
General Description
The HMC385LP4 & HMC385LP4E are GaAs InGaP
Heterojunction Bipolar Transistor (HBT) MMIC VCOs
with integrated resonators, negative resistance
devices, varactor diodes, and buffer amplifiers.
Covering 2.25 to 2.5 GHz, the VCO’s phase noise
performance is excellent over temperature, shock,
vibration and process due to the oscillator’s monolithic
structure. Power output is 4.5 dBm typical from a
single supply of 3V @ 35mA. The voltage controlled
oscillator is packaged in a low cost leadless QFN
4x4 mm surface mount package.
