HMC506LP4

MMIC VCO w/ BUFFER

AMPLIFIER, 7.8 - 8.7 GHz

Features

Pout: +14 dBm

Phase Noise: -103 dBc/Hz @100 KHz

No External Resonator Needed

Single Supply: +3V @ 77 mA

QFN Leadless SMT Package, 16 mm

General Description

The HMC506LP4 is a GaAs InGaP Heterojunc­tion Bipolar Transistor (HBT) MMIC VCO with
integrated resonator, negative resistance device,
varactor diode, and buffer amplifi er. Covering

7.8 to 8.7 GHz, the VCO’s phase noise perfor­mance is excellent over temperature, shock and
vibration due to the oscillator’s monolithic struc­ture. Power output is +14 dBm typical from a
single supply of +3.0V @ 77 mA. The voltage
controlled oscillator is packaged in a leadless
QFN 4 x 4 mm surface mount package.
