Product details
Overview
105706-HMC466LP4 from Analog Devices (formerly Hittite Microwave) is a GaAs InGaP HBT MMIC voltage-controlled oscillator with integrated buffer amplifier, operating from 6.1 to 6.72 GHz, delivering +4.5 dBm output power at +3 V/31 mA, and achieving −101 dBc/Hz phase noise at 100 kHz offset - used in microwave radio transceivers requiring stable, low-noise local oscillation.
For engineers reviewing the 105706-HMC466LP4 datasheet, 105706-HMC466LP4 pinout, 105706-HMC466LP4 application, or 105706-HMC466LP4 equivalent, key selection criteria include tuning voltage range (0–10 V), pulling sensitivity (11 MHz pp into 2.0:1 VSWR), pushing (30 MHz/V), frequency drift (0.8 MHz/°C), and QFN-24 package compatibility with RF ground paddle requirements.
Technical Context
This monolithic VCO integrates resonator, negative resistance device, varactor diode, and buffer amplifier on a single GaAs die, eliminating external tuning components. Its architecture ensures robust phase noise performance across temperature (−40°C to +85°C), shock, and vibration due to absence of discrete resonators or bond-wire dependencies.
The device uses a 24-lead 4×4 mm QFN package with exposed ground paddle requiring direct PCB RF grounding. Tuning is achieved via VTUNE (Pin 22) with 0–10 V control range, while RFOUT (Pin 16) provides AC-coupled 50 Ω output; supply is applied to Vcc (Pin 20) at +3 V nominal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 6.1–6.72 GHz - covers full C-band uplink for VSAT and point-to-point microwave radios. |
| Output Power | +4.5 dBm typical - sufficient to drive mixer LO ports without external amplification in compact RF front ends. |
| Phase Noise | −101 dBc/Hz @ 100 kHz offset - enables high-order QAM demodulation in 64-QAM broadcast relay systems. |
| Tuning Voltage | 0–10 V - compatible with standard DAC-based PLL loop filters and analog tuning circuits. |
| Supply Current | 31 mA @ +3 V - supports low-power portable test equipment and battery-backed industrial controllers. |
| Package | 24-lead 4×4 mm QFN with exposed ground paddle - requires thermal vias and RF ground plane per Hittite land pattern guidance. |
Pinout & Package
24-lead leadless QFN package (4 × 4 mm, 0.5 mm pitch) with exposed metal ground paddle; RoHS-compliant Sn finish; MSL1 rating; max reflow 235 °C; body material: low-stress injection molded plastic.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–14, 17–19, 21, 23, 24 | No Connection | Internally unconnected; must remain floating or tied to ground only if required by PCB EMI mitigation. |
| 15 | RF & DC Ground | Primary ground terminal; connects to exposed paddle - must be soldered directly to multilayer PCB ground plane with ≥6 thermal vias. |
| 16 | RF Output | AC-coupled 50 Ω output; requires series DC-blocking capacitor (e.g., 100 pF) before SMA connector or mixer input. |
| 20 | Supply Voltage | +3 V DC input; bypassed internally and externally (C1 = 4.7 μF tantalum + C2 = 10,000 pF) to suppress supply noise. |
| 22 | Tuning Voltage Input | 0–10 V analog control port; bandwidth limited by source impedance - recommended drive < 50 Ω for wideband FM modulation. |
Key Features
| Feature | Design Value |
|---|---|
| No external resonator required | Monolithic GaAs resonator eliminates tuning coil alignment, aging drift, and board space for discrete LC tanks. |
| Integrated buffer amplifier | Isolates oscillator core from load variations - maintains frequency stability under 2.0:1 VSWR mismatch conditions. |
| Low phase noise over temperature | −101 dBc/Hz @ 100 kHz maintained from −40°C to +85°C - avoids recalibration in outdoor microwave radios. |
| Single-supply operation | +3 V only - simplifies power architecture versus dual-rail VCOs and reduces BOM count in portable test gear. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar VCO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC466LP4E | RoHS-compliant; matte Sn finish; MSL1 with 260 °C reflow peak; identical electrical specs. | Required for lead-free manufacturing; same RF performance and pinout as 105706-HMC466LP4. | Select HMC466LP4E when RoHS compliance and higher reflow tolerance are mandatory. |
| HMC513LP5 | Wider tuning range (5.9–6.9 GHz); higher output (+6.5 dBm); −105 dBc/Hz phase noise; 5×5 mm QFN-32 package. | Supports broader frequency planning in military comms; requires PCB redesign due to larger footprint and extra pins. | Choose HMC513LP5 only when extended range or improved phase noise justifies layout change and cost increase. |
Compared with 105706-HMC466LP4, HMC466LP4E offers identical RF performance in a RoHS-compliant package, while HMC513LP5 delivers superior phase noise and bandwidth at the cost of larger size and non-pin-compatible layout - making 105706-HMC466LP4 optimal for cost-sensitive, space-constrained C-band designs.

FAQ
What is the operating temperature range for the 105706-HMC466LP4?
The 105706-HMC466LP4 operates from −40°C to +85°C ambient temperature. Its monolithic GaAs structure ensures stable frequency and phase noise performance across this full industrial range without external compensation. The device's frequency drift is specified at 0.8 MHz/°C, and phase noise remains −101 dBc/Hz @ 100 kHz offset even at temperature extremes. Thermal design must ensure the channel temperature stays below 135°C per absolute maximum ratings.
Does the 105706-HMC466LP4 require an external resonator or tuning components?
No, the 105706-HMC466LP4 does not require any external resonator or tuning components. It integrates a monolithic GaAs resonator, varactor diode, negative resistance device, and buffer amplifier on a single die. This eliminates coil alignment, aging-related drift, and PCB real estate typically needed for discrete LC tanks - enabling faster time-to-market and higher reliability in microwave radio and VSAT applications.
What is the recommended PCB grounding practice for the 105706-HMC466LP4?
The 105706-HMC466LP4 requires direct RF and DC grounding of Pin 15 and the exposed metal paddle beneath the package. At least six thermal vias (0.3 mm diameter, spaced ≤1 mm apart) must connect the paddle to an internal or bottom-layer solid ground plane. Signal traces should maintain 50 Ω impedance, and all ground leads (Pins 1–14, 17–19, 21, 23, 24) must be tied to the same ground plane - per Hittite Application Note for land pattern guidance.
Can the 105706-HMC466LP4 be used with a 5 V supply?
No, the 105706-HMC466LP4 is rated for +3 V nominal supply (absolute maximum +3.5 V). Operating above +3.5 V risks permanent damage. Supply current increases linearly with voltage: 22 mA at 2.75 V, 31 mA at 3.0 V, and 41 mA at 3.25 V. For 5 V systems, a dedicated low-noise LDO regulator must step down to +3 V, with appropriate decoupling (4.7 μF tantalum + 10,000 pF ceramic) placed within 2 mm of Pin 20.
What is the function of Pin 22 (VTUNE) on the 105706-HMC466LP4?
Pin 22 (VTUNE) is the analog control voltage input that sets the output frequency between 6.1 and 6.72 GHz. It accepts 0–10 V DC with 10 μA leakage current. Tuning sensitivity is 30 MHz/V near mid-range, and pushing is characterized at 30 MHz/V when Vtune = +5 V. Drive source impedance affects modulation bandwidth - low-impedance (<50 Ω) sources are recommended for wideband FM applications using the 105706-HMC466LP4.
