HMC429LP4 / 429LP4E
MMIC VCO w/ BUFFER AMPLIFIER, 4.45 - 5.0 GHz
Features
Pout: +4.0 dBm Phase Noise: -105 dBc/Hz @100 KHz No External Resonator Needed Single Supply: 3V @ 30 mA QFN Leadless SMT Package, 16 mm2
General Description
The HMC429LP4 & HMC429LP4E are GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs with integrated resonators, negative resistance devices, varactor diodes, and buffer amplifiers. Covering 4.45 to 5.0 GHz, the VCO’s phase noise performance is excellent over temperature, shock, vibration and process due to the oscillator’s monolithic structure.
