Product details
Overview
HMC511LP5 from Analog Devices (formerly Hittite Microwave) is a GaAs InGaP HBT MMIC voltage-controlled oscillator with dual AC-coupled RF outputs: fundamental (9.05–10.15 GHz) and half-frequency (4.525–5.075 GHz). It delivers +13 dBm typical output power from a +5 V supply, achieves –115 dBc/Hz phase noise at 100 kHz offset, and operates over –40°C to +85°C for VSAT and point-to-point radio transceivers.
For engineers reviewing the HMC511LP5 datasheet, HMC511LP5 pinout, HMC511LP5 application, or HMC511LP5 equivalent, this page provides verified specifications, package layout, real-world use cases, and validated alternative VCOs for microwave frequency synthesis in ruggedized RF systems.
Technical Context
The HMC511LP5 integrates monolithic resonators, negative resistance devices, and varactor diodes in a single GaAs die, eliminating external tuning components. Its fully integrated architecture ensures stable phase noise performance across temperature, shock, and process variation.
It features two independent RF outputs-RFOUT (Fo) and RFOUT/2-with matched thermal drift and simultaneous operation. Tuning sensitivity ranges from ~15 MHz/V near mid-band to higher values at band edges, and pulling is limited to 8 MHz peak-to-peak into 2.0:1 VSWR.

Equivalent & Alternatives
The following parts are listed as comparable options for similar VCO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC512LP5 | Same 5×5 QFN package; wider Fo range (8.5–9.6 GHz); lower phase noise (–117 dBc/Hz @ 100 kHz). | Optimized for 8–9 GHz radar bands; lacks Fo/2 output-requires external divider for sub-harmonic LO. | Select when primary need is lower phase noise in 8.5–9.6 GHz band and Fo/2 is not required. |
| LMX2594RHAR | Wideband PLL+VCO IC (10 MHz–15 GHz); integrated fractional-N synthesizer; requires external loop filter. | Enables programmable frequency steps and digital tuning; higher integration but larger solution size and higher current draw (320 mA). | Select when digital frequency control, fine resolution, or multi-band agility outweighs analog simplicity and power efficiency. |
Compared with HMC511LP5, HMC512LP5 offers superior phase noise in a narrower band without Fo/2, while LMX2594RHAR adds digital programmability at the cost of increased complexity and power-making HMC511LP5 optimal for fixed-band, low-noise, dual-output analog RF systems.

FAQ
What is the recommended PCB grounding strategy for HMC511LP5?
Per Hittite's evaluation board design, the exposed ground paddle (pins 5 and 11) must be soldered to a solid RF ground plane using multiple thermal vias. All no-connect pins may also be grounded to enhance shielding. The PCB should use 50 Ω controlled-impedance routing for RFOUT and RFOUT/2 traces, and separate low-inductance paths for Vcc and VTUNE decoupling capacitors. This ensures optimal thermal dissipation, phase noise, and output power stability for the HMC511LP5.
Does HMC511LP5 require external matching components?
No. The HMC511LP5 is a fully integrated MMIC VCO with on-die resonators, varactors, and negative resistance devices. Its RFOUT and RFOUT/2 outputs are internally matched to 50 Ω and AC-coupled, so no external matching networks, baluns, or resonators are needed. The only required external components are DC blocking capacitors (if interfacing with biased stages) and standard supply decoupling (100 pF + 1000 pF per Hittite's eval board layout for the HMC511LP5).
What is the maximum allowable tuning voltage for HMC511LP5?
The absolute maximum rating for VTUNE is +15 V DC. However, the specified operational tuning range is 2–13 V, within which full 9.05–10.15 GHz coverage is guaranteed. Operating above 13 V may cause excessive current draw or accelerated aging without improving frequency range. The HMC511LP5 datasheet specifies 10 µA max leakage at 13 V, confirming safe biasing within this limit.
How does phase noise performance of HMC511LP5 vary with temperature?
The HMC511LP5 maintains –115 dBc/Hz typical phase noise at 100 kHz offset across its full operating range (–40°C to +85°C), as confirmed by characterization plots in the datasheet. This stability results from monolithic GaAs integration, which minimizes thermal gradients between resonator and active devices. No external compensation or calibration is required to sustain this performance for the HMC511LP5 in field-deployed systems.
Is HMC511LP5 pin-compatible with HMC511LP5E?
Yes. HMC511LP5 and HMC511LP5E share identical pinout, footprint, and electrical specifications. The only differences are RoHS compliance (matte Sn vs. Sn/Pb finish) and MSL3 reflow profile (260°C peak for HMC511LP5E vs. 235°C for HMC511LP5). Both versions use the same 5×5 mm QFN package and are interchangeable in layout and circuit design for the HMC511LP5.
