Product Overview
HMC508LP5ETR is high-performance GaAs InGaP HBT MMIC VCO with built-in divide-by-2 prescaler from ADI (Hittite). Operating 7.3–8.2 GHz with 3.65–4.1 GHz divided output, it integrates resonator, varactor, buffer and divider on one die to simplify microwave LO design. Running on 5V supply with +5 dBm typical output, it delivers ultra-low phase noise and low microphonics. Packaged in 5×5mm 32-lead RoHS QFN, tape & reel shipping for radio, VSAT and military microwave gear.
Core Advantages
Integrated Divide-by-2 Prescaler
Onboard frequency divider reduces primary oscillation frequency, matching low-cost low-frequency PLL chips to build high-precision phase-locked loop easily.
Ultra-Low Phase Noise Architecture
Adopts proprietary InGaP HBT process, phase noise reaches -113 dBc/Hz at 100 kHz offset, effectively reducing signal jitter for high-order modulation communication systems.
Highly Integrated Monolithic Design
Varactor tuning diode, resonator node, buffer amplifier and prescaler integrated on one chip, stable thermal performance without complicated external peripheral circuits.
Stable Output Power & Load Isolation
Delivers steady +5 dBm typical output power in full tuning range. Internal buffer isolates oscillator core from load changes, maintaining stable frequency performance.
