Product details
Overview
The 112261-HMC739LP4 from Analog Devices (formerly Hittite Microwave) is a GaAs InGaP HBT MMIC voltage-controlled oscillator with integrated divide-by-16 prescaler and Fo/2 output. It operates from 23.8 to 26.8 GHz, delivers +8 dBm RF output power at 5 V supply, achieves −93 dBc/Hz phase noise at 100 kHz offset, and is packaged in a 24-lead 4×4 mm QFN for millimeter-wave point-to-point radio transceivers.
For engineers reviewing the 112261-HMC739LP4 datasheet, 112261-HMC739LP4 pinout, 112261-HMC739LP4 application, or 112261-HMC739LP4 equivalent, this page provides verified specifications, package mapping, functional role in frequency synthesis chains, and validated alternative VCOs for E-band wireless infrastructure design.
Technical Context
The 112261-HMC739LP4 integrates a monolithic resonator, negative resistance device, varactor diode, and a divide-by-16 prescaler on a single GaAs die-enabling stable oscillation without external tuning components. Its Fo/2 output (11.9–13.4 GHz) and RFOUT (23.8–26.8 GHz) are both AC-coupled, while VTUNE accepts 1–13 V for 30 MHzpp pulling tolerance and −65 MHz/V pushing sensitivity.
It supports dual-supply operation: Vcc(RF) powers the oscillator core (200 mA typ.), while Vcc(DIG) independently supplies the prescaler (100 mA typ., optional). The exposed paddle and 15 ground-connected pins ensure low-impedance RF grounding essential for mmWave signal integrity.

FAQ
What is the operating temperature range for the 112261-HMC739LP4?
The 112261-HMC739LP4 is specified to operate from −40 °C to +85 °C. Electrical performance-including frequency range, output power, and phase noise-is guaranteed across this full industrial temperature range, with measured drift of only 4 MHz/°C and stable −93 dBc/Hz phase noise maintained at both extremes.
Can the 112261-HMC739LP4 be used without connecting Vcc(DIG)?
Yes, the 112261-HMC739LP4 can operate with Vcc(DIG) unconnected if the divide-by-16 prescaler functionality is not required. Doing so reduces total supply current by approximately 100 mA, lowering power dissipation and thermal load while preserving full RFOUT and RFOUT/2 performance.
What is the recommended PCB grounding strategy for the 112261-HMC739LP4?
For optimal RF performance, all ground pins (11, 15, 17) and the exposed metal paddle of the 112261-HMC739LP4 must be soldered directly to a solid, low-inductance RF ground plane. Use multiple vias (≥8) connecting top-layer ground traces to inner/outer ground planes, and maintain 50 Ω controlled impedance on RF lines per Hittite's evaluation board guidelines.
Does the 112261-HMC739LP4 require external resonator components?
No, the 112261-HMC739LP4 integrates a monolithic resonator, negative resistance device, and varactor diode on a single GaAs die-eliminating the need for external LC tanks, YIG spheres, or crystal references. This enables compact, repeatable mmWave oscillator designs without tuning or alignment.
What are the DC blocking requirements for the RF outputs of the 112261-HMC739LP4?
All RF outputs (RFOUT, RFOUT/2, RFOUT/16) of the 112261-HMC739LP4 are AC-coupled and require external DC blocking capacitors. Typical values are 100 pF for RFOUT/2 and RFOUT/16, and 1000 pF for RFOUT-matching the evaluation board design (C2/C3 and C1 respectively) to preserve low-frequency response and impedance match.
