Product details
Overview
HMC529LP5 from Analog Devices (formerly Hittite Microwave) is a GaAs InGaP HBT MMIC voltage-controlled oscillator with integrated divide-by-4 and half-frequency outputs, operating at 12.4–13.4 GHz (RFOUT), 6.2–6.7 GHz (RFOUT/2), and 3.1–3.35 GHz (RFOUT/4). It delivers +8 dBm RF output power at +5 V supply, exhibits −110 dBc/Hz phase noise at 100 kHz offset, and is packaged in a 32-lead 5×5 mm QFN for VSAT and point-to-point radio transceivers.
For engineers reviewing the HMC529LP5 datasheet, HMC529LP5 pinout, HMC529LP5 application, or HMC529LP5 equivalent, this page provides verified functional roles, validated dual-band output behavior, confirmed thermal and tuning voltage limits (−40°C to +85°C, 2–13 V), package grounding requirements, and real-world prescaler disable capability for current optimization.
Technical Context
The HMC529LP5 integrates monolithic resonators, varactor diodes, and negative resistance devices on a single GaAs InGaP HBT die, enabling stable oscillation without external tuning components. Its three AC-coupled RF outputs-fundamental (Fo), half-frequency (Fo/2), and divide-by-4 (Fo/4)-are simultaneously active and internally buffered.
Phase noise performance is stabilized across temperature (−40°C to +85°C) and supply variation (4.75–5.25 V) due to its monolithic architecture. The prescaler section (Vcc1) can be left open to reduce total supply current by ~65 mA, while VTUNE supports FM modulation with bandwidth dependent on source impedance.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar VCO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC513LP5 | Single-output (Fo only), 10.5–11.5 GHz range; no Fo/2 or Fo/4; lower phase noise (−112 dBc/Hz) | Lacks dual-band output capability; suitable only where Fo-only operation suffices | Select when system requires higher spectral purity at narrower bandwidth and does not need divided outputs |
| HMC586LC4B | Wider Fo range (12.5–14.5 GHz); single-output; higher Pout (+10 dBm); no internal divider | Requires external dividers for Fo/2/Fo/4; larger 4×4 mm package; higher current draw (320 mA) | Choose when broader tuning range and higher output power are prioritized over integrated division and compact footprint |
Compared with HMC529LP5, HMC513LP5 offers superior phase noise but lacks frequency division functionality, while HMC586LC4B extends tuning range and output power at the cost of added external circuitry and board space-making HMC529LP5 optimal for space-constrained dual-band radios needing integrated division.

FAQ
What is the operating temperature range for the HMC529LP5?
The HMC529LP5 operates reliably from −40°C to +85°C. Its monolithic GaAs InGaP HBT structure ensures stable frequency and phase noise performance across this full industrial/military temperature range, with measured frequency drift of only 1.2 MHz/°C and phase noise variation less than 2 dB over temperature.
Can the prescaler function of the HMC529LP5 be disabled to reduce power consumption?
Yes, the prescaler function in the HMC529LP5 can be disabled by leaving pin 6 (Vcc1) unconnected, reducing total supply current by approximately 65 mA. This configuration maintains full Fo and Fo/2 output functionality while lowering overall power draw-ideal for battery-powered test equipment or thermally constrained modules.
Does the HMC529LP5 require external matching components for RF output?
No, the HMC529LP5 requires no external matching components. All RF outputs (RFOUT, RFOUT/2, RFOUT/4) are internally matched to 50 Ω and AC-coupled. The device is designed for direct connection to SMA connectors or 50 Ω microstrip traces, provided the PCB ground paddle and leads are properly soldered to a low-inductance RF ground plane.
What is the absolute maximum tuning voltage for the HMC529LP5?
The absolute maximum tuning voltage for the HMC529LP5 is +15 V applied to pin 29 (VTUNE). Operation beyond this limit risks permanent damage. For reliable performance, the recommended tuning range is 2–13 V, delivering full 12.4–13.4 GHz coverage with linearity suitable for analog FM and digital frequency modulation schemes.
How is the exposed ground paddle of the HMC529LP5 package used in PCB layout?
The exposed ground paddle of the HMC529LP5 must be soldered directly to the PCB's RF ground plane using multiple thermal vias (≥8 recommended). Per Hittite Application Note guidance, this connection is mandatory-not optional-to ensure proper RF return path, thermal dissipation (θJA = 27°C/W), and suppression of spurious emissions caused by ground inductance.
