Product details
Overview
HMC533LP4 from Analog Devices (formerly Hittite Microwave) is a GaAs InGaP HBT MMIC voltage-controlled oscillator with integrated divide-by-16 prescaler, operating from 23.8 to 24.8 GHz. It delivers +12 dBm RF output power at +5 V supply, exhibits −95 dBc/Hz phase noise at 100 kHz offset, and uses a 24-lead 4×4 mm QFN package. It serves as the core frequency source in millimeter-wave VSAT and automotive radar transceivers.
For engineers reviewing the HMC533LP4 datasheet, HMC533LP4 pinout, HMC533LP4 application, or HMC533LP4 equivalent, key selection criteria include its 24 GHz band coverage, monolithic VCO architecture eliminating external resonators, −95 dBc/Hz phase noise performance across temperature, and prescaler disable capability for current optimization in low-power systems.
Technical Context
The HMC533LP4 integrates resonators, negative resistance devices, and varactor diodes on a single GaAs die, enabling stable oscillation without external tuning components. Its monolithic construction ensures consistent phase noise performance over −40°C to +85°C and under mechanical shock.
It provides two RF outputs: fundamental RFOUT (23.8–24.8 GHz, +12 dBm typ.) and divided RFOUT/16 (1.437–1.562 GHz, −4 dBm typ.). The prescaler can be disabled by leaving VCC2/VCC3 unconnected, reducing supply current by ~100 mA.

Equivalent & Alternatives
The following parts are listed as comparable options for similar VCO-with-divider applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC532LP4 | 22.5–23.5 GHz range, same 4×4 mm QFN package, identical pinout and prescaler architecture. | Lower-frequency alternative for 23 GHz band systems; lacks coverage for 24 GHz VSAT or radar. | Select when system frequency plan centers below 23.5 GHz and board layout reuse is prioritized. |
| ADF4371BCPZ | Integrated PLL+VCO+divider in 32-lead LFCSP; synthesizes 23.8–24.8 GHz but requires external loop filter and reference clock. | Enables programmable frequency steps and fractional-N synthesis; higher integration but greater design complexity. | Select when fine frequency resolution (<1 Hz), programmability, or multi-band support outweighs simplicity and phase noise advantage of standalone VCO. |
Compared with HMC533LP4, HMC532LP4 offers identical architecture at lower frequency, while ADF4371BCPZ trades monolithic simplicity for synthesizer flexibility - choice depends on whether fixed-frequency stability or programmable agility is primary.

FAQ
What is the operating frequency range of the HMC533LP4?
The HMC533LP4 operates from 23.8 GHz to 24.8 GHz at its fundamental RFOUT pin. This 1 GHz bandwidth supports E-band applications including 24 GHz automotive radar and unlicensed point-to-point radio. The divided output (RFOUT/16) ranges from 1.437 GHz to 1.562 GHz, verified across the full tuning voltage range and temperature specification.
Does the HMC533LP4 require an external resonator or tuning components?
No, the HMC533LP4 does not require any external resonator, varactor, or tuning inductors. Its GaAs InGaP HBT monolithic structure integrates resonators, negative resistance devices, and varactor diodes - enabling self-contained oscillation across its full 23.8–24.8 GHz range with only DC bias and tuning voltage applied.
How is the prescaler function disabled on the HMC533LP4?
The prescaler on the HMC533LP4 is disabled by leaving pins 3 (VCC2) and 4 (VCC3) unconnected. This reduces total supply current from 220 mA to approximately 120 mA, conserving power in applications where only the fundamental RFOUT is needed and the divided output is unused.
What is the recommended grounding method for the HMC533LP4 QFN package?
The HMC533LP4 requires RF grounding of all GND pins (1, 15, 17, 21, 23) and the exposed metal paddle on the package bottom. Per Hittite Application Note guidance, the paddle must be soldered to a solid PCB ground plane using multiple thermal vias to ensure optimal phase noise, thermal dissipation, and output power stability.
What is the phase noise performance of the HMC533LP4 and under what conditions is it specified?
The HMC533LP4 delivers −95 dBc/Hz typical SSB phase noise at a 100 kHz offset from the carrier, measured at RFOUT with VTUNE = +5 V, VCC = +5 V, and TA = +25°C. This performance is maintained across the full −40°C to +85°C operating temperature range, confirmed by characterization data in the official datasheet revision v00.0405.
