HMC505LP4 / 505LP4E
MMIC VCO w/ BUFFER AMPLIFIER, 6.8 - 7.4 GHz
Features
Pout: +11dBm Phase Noise: -106 dBc/Hz @100 kHz No External Resonator Needed Single Supply: +3V @ 80 mA QFN Leadless SMT Package, 16mm2
General Description
The HMC505LP4 & HMC505LP4E are GaAs InGaP Heterojunction Bipolar
Transistor (HBT) MMIC VCOs with integrated resonators, negative resistance devices, varactor diodes, and buffer amplifiers. Covering 6.8 to 7.4 GHz, the VCO’s phase noise performance is excellent over temperature, shock and vibration due to the oscillator’s monolithic structure. Power output is +11 dBm typical from a single supply of +3V @ 80 mA. The voltage controlled oscillator is packaged in a leadless QFN 4x4 mm surface mount package.
