Product Overview
The HMC511LP5ETR is a high-performance GaAs HBT MMIC VCO from Analog Devices (formerly Hittite). This dual-band oscillator covers 9.05–10.15 GHz fundamental frequency, with built-in divide-by-2 circuit offering 4.525–5.075 GHz half-frequency output. It operates at nominal 5V supply (4.75V~5.25V) and features low phase noise of -115 dBc/Hz @100 kHz offset. Housed in a compact 5×5 mm 32-VFQFN package with exposed thermal pad, no external resonator needed, suitable as local oscillator for microwave radio, VSAT, test instruments and radar systems.
Core Advantages
Integrated Divide-by-2 Half-Frequency Output
Built-in frequency divider generates 4.525~5.075 GHz signal, simplifying PLL design and lowering requirements for high-frequency prescalers.
Excellent Low SSB Phase Noise
GaAs HBT process achieves -115 dBc/Hz @100 kHz offset, reducing signal jitter and improving system signal-to-noise performance.
Fully Integrated Single-Chip VCO
Onboard resonator, varactor diode and buffer amplifier, removes extra resonant components and saves PCB layout space.
Compact Thermal Enhanced Package
5×5 mm SMD 32-VFQFN with exposed ground pad, delivering superior high-frequency grounding and heat dissipation.

Frequently Asked Questions
Q1: What does suffix “ETR” mean in HMC511LP5ETR?
A: LP5 = 5×5mm QFN package; E = RoHS lead-free; TR stands for tape & reel packaging (7-inch reel, 500 pcs/reel).
Q2: What is the function of the built-in divide-by-2 circuit?
A: It outputs 4.525~5.075 GHz low-frequency signal, allowing designers to adopt low-cost PLL chips instead of expensive high-frequency prescalers.
Q3: What tuning voltage covers the full frequency range?
A: 2.0V ~ 13.0V tuning voltage is required to sweep complete 9.05–10.15 GHz fundamental band.
Q4: Must the exposed thermal pad be fully soldered?
A: Yes. The exposed pad serves as RF ground and heat sink. Complete soldering with thermal vias is required for stable RF performance and heat dissipation.
Q5: Are there pin-to-pin compatible replacement models?
A: No official direct drop-in replacement from ADI. Alternative option: HMC510LP5E (X-band VCO, verify frequency range). Qorvo / Skyworks equivalent VCOs need PCB redesign and circuit tuning.
Q6: Can this VCO work under 3V power supply?
A: Not supported. Nominal supply voltage is 5V (4.75V~5.25V). Low voltage causes unstable oscillation, insufficient output power and frequency drift.
Q7: Difference between HMC511LP5E and HMC511LP5ETR?
A: Same die and electrical parameters. LP5E is tray packing; LP5ETR is tape & reel for automated SMT assembly.
Q8: What storage rules should be followed?
A: This device is MSL 3 moisture-sensitive. Bake process is mandatory once the dry bag is opened over 168 hours before soldering.
Q9: Can I use only part of the frequency tuning range?
A: Yes. You can limit Vtune voltage to lock partial frequency band, but keep voltage within 2V~13V to avoid device damage.
