Product details
Overview
The 110227-HMC735LP5 from Hittite Microwave (now Analog Devices) is a GaAs InGaP HBT MMIC voltage-controlled oscillator with integrated divide-by-4 prescaler, operating from 10.5–12.2 GHz at RFOUT and 2.625–3.05 GHz at RFOUT/4, delivering +17 dBm output power from +5 V, with −100 dBc/Hz phase noise @ 100 kHz offset, used in SATCOM transceivers and point-to-point radio front-ends.
For engineers reviewing the 110227-HMC735LP5 datasheet, 110227-HMC735LP5 pinout, 110227-HMC735LP5 application, or 110227-HMC735LP5 equivalent, key selection criteria include dual-band VCO+prescaler integration, 32-pin 5×5 mm QFN package compatibility, tuning voltage range (1–13 V), supply current (180–240 mA), and RFOUT/4 harmonic suppression (−40 dBc third harmonic).
Technical Context
This monolithic VCO integrates resonators, negative resistance devices, and varactor diodes on a single GaAs die, eliminating external tuning components. Its divide-by-4 prescaler operates independently and can be disabled via Vcc(Dig) to reduce current draw by ~100 mA.
The oscillator exhibits low pulling (50 MHz pp into 2.0:1 VSWR) and pushing (30 MHz/V), with frequency drift of 1.4 MHz/°C over −40 to +85 °C. Phase noise stability across temperature is enabled by the monolithic HBT structure, not external compensation.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar VCO-with-prescaler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC736LP5E | Wider tuning range (11.0–12.8 GHz RFOUT); higher phase noise (−98 dBc/Hz @ 100 kHz); RoHS-compliant matte Sn finish | Optimized for higher-frequency SATCOM uplinks; requires tighter layout control due to reduced phase margin | Select when targeting 12.5 GHz uplink bands and RoHS compliance is mandatory |
| ADF4371BCPZ | PLL+VCO IC with integrated fractional-N synthesizer; 10–16 GHz output; requires external loop filter and reference clock | Provides programmable frequency steps and digital interface; adds complexity but enables precise channel spacing | Select when fine frequency resolution (<1 Hz step) and SPI control are required over raw VCO simplicity |
Compared with HMC736LP5E and ADF4371BCPZ, the 110227-HMC735LP5 offers the lowest phase noise and simplest analog interface among Ku-band VCO+prescaler solutions, making it optimal for fixed-frequency, high-spectral-purity applications where layout space and power efficiency are constrained.

FAQ
What is the recommended PCB grounding strategy for the 110227-HMC735LP5?
Per the manufacturer's application note, all ground pins (pins 5, 11, 18) and the exposed metal paddle must be soldered directly to a solid RF/DC ground plane using multiple thermal vias. The evaluation board (110225) uses Rogers 4350 substrate with dense via stitching between top and bottom ground layers to maintain <0.1 Ω RF ground impedance, critical for suppressing spurious emissions in the 110227-HMC735LP5.
Can the 110227-HMC735LP5 operate without the prescaler enabled?
Yes - the 110227-HMC735LP5 prescaler is powered separately via pin 6 (Vcc(Dig)). Leaving this pin unconnected disables the /4 divider, reducing total supply current from ~217 mA to ~117 mA while preserving full 10.5–12.2 GHz RFOUT functionality. This mode is validated in the datasheet's electrical specifications table under "Supply Current" conditions.
What is the maximum allowable tuning voltage for the 110227-HMC735LP5?
The absolute maximum rating for VTUNE is +15 V, but the functional tuning range is specified as 1–13 V for linear frequency control across the full 10.5–12.2 GHz band. Applying >13 V may cause varactor breakdown or accelerated aging; the 110227-HMC735LP5 datasheet confirms stable operation only within the 1–13 V range for guaranteed performance.
Does the 110227-HMC735LP5 require external matching components?
No - the 110227-HMC735LP5 is fully matched internally: its RFOUT and RFOUT/4 outputs are designed for direct 50 Ω termination, and no external resonators, capacitors, or inductors are needed for basic operation. The datasheet explicitly states "requires no external matching components," verified by S-parameter measurements across temperature and process corners.
How does temperature affect the 110227-HMC735LP5's output frequency stability?
The 110227-HMC735LP5 exhibits a frequency drift rate of 1.4 MHz/°C over −40 to +85 °C, measured at Vtune = +5 V. This drift is linear and predictable, enabling simple calibration in closed-loop PLL systems. Phase noise remains stable across temperature due to the monolithic GaAs HBT structure - no external compensation circuitry is required for the 110227-HMC735LP5 to meet spec over its full operating range.
