Product details
Overview
105706-HMC506LP4 from Analog Devices (formerly Hittite Microwave) is a GaAs InGaP HBT MMIC voltage-controlled oscillator with integrated buffer amplifier, operating from 7.8 to 8.7 GHz. It delivers +14 dBm typical RF output power at +3.0 V supply (77 mA), achieves −103 dBc/Hz SSB phase noise at 100 kHz offset, and requires no external resonator. It serves as a low-noise local oscillator in VSAT radio transceivers.
For engineers reviewing the 105706-HMC506LP4 datasheet, 105706-HMC506LP4 pinout, 105706-HMC506LP4 application, or 105706-HMC506LP4 equivalent, key selection criteria include its monolithic VCO architecture, 77 mA supply current at 3 V, 7.8–8.7 GHz tuning range, −103 dBc/Hz phase noise at 100 kHz, and QFN-16 leadless SMT package compatibility with RF ground-paddle layout requirements.
Technical Context
The 105706-HMC506LP4 integrates a negative-resistance oscillator core, varactor tuning diode, and buffer amplifier on a single GaAs die, eliminating external resonators and reducing board-level phase noise sensitivity to vibration and thermal drift. Its monolithic construction ensures stable frequency drift of only 0.85 MHz/°C and pulling of ≤28 MHz peak-to-peak into 2.0:1 VSWR.
It operates from a single +3.0 V supply with 77 mA typical current draw and accepts a 1–11 V tuning voltage (VTUNE) across a 16-pin QFN package where pins 1–14, 17–19, 21, 23, and 24 are NC, pin 15 is GND, pin 16 is AC-coupled RFOUT, pin 20 is VCC, and pin 22 is VTUNE.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar VCO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC506LP4E | RoHS-compliant variant with 100% matte Sn finish and MSL1 rating; identical electrical specs and pinout | Required for lead-free assembly processes; same thermal resistance (165 °C/W) and tuning behavior | Select HMC506LP4E when RoHS compliance and 260 °C reflow capability are mandatory |

FAQ
What is the operating frequency range of the 105706-HMC506LP4?
The 105706-HMC506LP4 operates from 7.8 to 8.7 GHz, covering the lower portion of the Ku-band. This range is fully specified across temperature (−40°C to +85°C) and supply voltage (2.75–3.25 V), with monotonic tuning response and ≤28 MHz peak-to-peak pulling into 2.0:1 VSWR. The 105706-HMC506LP4 is optimized for fixed-frequency or narrowband agile applications in satellite and terrestrial microwave systems.
Does the 105706-HMC506LP4 require external tuning components?
No, the 105706-HMC506LP4 integrates all resonant elements, negative-resistance devices, and varactor diodes on a single GaAs die, eliminating the need for external inductors, capacitors, or tuning diodes. Only DC blocking at RFOUT and supply decoupling at VCC are required. The 105706-HMC506LP4 achieves this through monolithic HBT process design, enabling repeatable performance without manual alignment.
What is the recommended PCB layout practice for the 105706-HMC506LP4 ground paddle?
The exposed ground paddle of the 105706-HMC506LP4 must be soldered directly to a solid RF ground plane using multiple thermal vias (≥8, 0.3 mm diameter) spaced ≤2 mm apart. Per Hittite Application Note, this minimizes inductance and maintains output return loss ≥7 dB. The 105706-HMC506LP4 evaluation board (P/N 105667) uses Rogers 4350 substrate and follows this grounding scheme.
How does phase noise performance of the 105706-HMC506LP4 vary with temperature?
The 105706-HMC506LP4 maintains −103 dBc/Hz SSB phase noise at 100 kHz offset from carrier across −40°C to +85°C, with only minor degradation (<1 dB) at extremes. This stability results from monolithic thermal coupling between oscillator core and buffer amplifier. Measured data shows <0.5 dB variance in phase noise from +25°C to +85°C at VTUNE = +5 V, confirming suitability for uncooled outdoor deployments.
Is the 105706-HMC506LP4 pin-compatible with other Hittite VCOs like the HMC512LP5?
No, the 105706-HMC506LP4 is not pin-compatible with the HMC512LP5. While both are QFN-packaged VCOs, the 105706-HMC506LP4 uses a 16-pin configuration (4 × 4 mm), whereas the HMC512LP5 uses a 20-pin QFN (5 × 5 mm). Pin functions differ: the 105706-HMC506LP4 has dedicated VTUNE on pin 22 and RFOUT on pin 16, while the HMC512LP5 assigns these to different locations and adds additional bias/control pins.
