Product details
Overview
105706-HMC430LP4 from Analog Devices (formerly Hittite Microwave) is a GaAs InGaP HBT MMIC voltage-controlled oscillator with integrated resonator and buffer amplifier, operating in the 5.0–5.5 GHz C-band range. It delivers +2 dBm RF output at 3 V supply, exhibits −103 dBc/Hz phase noise at 100 kHz offset, and requires no external resonator-enabling compact, low-noise local oscillator synthesis for wireless radios.
For engineers reviewing the 105706-HMC430LP4 datasheet, 105706-HMC430LP4 pinout, 105706-HMC430LP4 application, or 105706-HMC430LP4 equivalent, key selection criteria include its monolithic VCO architecture, 4×4 mm QFN package with exposed ground paddle, 0–10 V tuning range, ±12 MHz/V pushing sensitivity, and −40°C to +85°C operational temperature range.
Technical Context
The 105706-HMC430LP4 integrates a negative-resistance oscillator core, varactor tuning diode, and buffer amplifier on a single GaAs die, eliminating external resonators and reducing layout sensitivity. Its monolithic construction ensures stable phase noise performance across temperature, shock, and vibration-critical for C-band point-to-point and VSAT systems.
It operates from a single 3 V supply drawing 27 mA typical, with tuning voltage applied to Pin 22 (VTUNE) and RF output delivered AC-coupled from Pin 16 (RFOUT). The device features 6 dB output return loss and −15 dBc/−25 dBc 2nd/3rd harmonic suppression, supporting direct interface to mixers or prescalers without filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 5.0–5.5 GHz - fixed C-band coverage suitable for UNII-3, HiperLAN, and VSAT uplink/downlink channels. |
| Output Power | +2 dBm typical - sufficient to drive passive mixers or low-gain IF stages without external amplification. |
| Phase Noise @ 100 kHz | −103 dBc/Hz - enables <1% EVM in 64-QAM 802.11a systems at 5.4 GHz with minimal adjacent-channel interference. |
| Tuning Voltage Range | 0–10 V - compatible with standard DACs or analog control loops; supports full band coverage with linear frequency response. |
| Supply Current | 27 mA @ 3 V - low power consumption enables integration into battery-assisted or thermally constrained RF modules. |
| Package | 4×4 mm QFN-24 with exposed ground paddle - requires RF grounding via multiple vias; MSL1, Sn/Pb finish, 235 °C peak reflow. |
| Operating Temp | −40°C to +85°C - qualified for outdoor wireless infrastructure and industrial-grade radio terminals. |
Pinout & Package
105706-HMC430LP4 is housed in a 4×4 mm, 24-pin leadless QFN package with an exposed metal ground paddle on the bottom. All ground pins (1–14, 17–19, 21, 23, 24) and the paddle must be soldered to PCB RF ground per Hittite's land pattern recommendation.
| 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 mechanical stability. |
| 15 | Ground | Primary RF/DC ground reference; connects directly to exposed paddle and system ground plane. |
| 16 | RF Output | AC-coupled 50 Ω output port; requires series DC-blocking capacitor before downstream components. |
| 20 | Supply Voltage | 3 V DC input; bypass with 4.7 μF tantalum + 10,000 pF ceramic per evaluation board design. |
| 22 | Tuning Voltage | 0–10 V analog control input; bandwidth limited by source impedance; sensitive to noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| No external resonator required | Monolithic resonator integration eliminates discrete inductor/capacitor tuning networks and associated layout sensitivity. |
| Excellent phase noise stability | −103 dBc/Hz @ 100 kHz maintained over −40°C to +85°C, shock, and vibration due to monolithic GaAs HBT structure. |
| Integrated buffer amplifier | Isolates oscillator core from load variations, enabling consistent frequency stability into 2:1 VSWR (12 MHz pp pulling). |
| Low supply current | 27 mA at 3 V allows use in power-constrained RF front-ends without thermal derating or heatsinking. |
| QFN-24 with exposed paddle | Enables robust RF grounding and thermal dissipation (θJA = 482 °C/W); compatible with automated SMT assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar VCO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC430LP4E | RoHS-compliant version with 100% matte tin finish and 260 °C peak reflow rating; identical electrical specs and pinout. | Required for lead-free manufacturing; same C-band performance but different thermal profile during reflow. | Select HMC430LP4E when RoHS compliance and Pb-free assembly are mandatory; otherwise HMC430LP4 is cost-optimized. |
| HMC513LP5 | Wider 4.8–5.7 GHz range, −105 dBc/Hz phase noise @ 100 kHz, 3.3 V supply, 5×5 mm QFN-32 package. | Supports broader UNII band coverage and higher linearity; requires PCB redesign due to larger footprint and extra pins. | Choose HMC513LP5 when extended frequency coverage or improved phase noise is critical and board space permits. |
Compared with HMC430LP4E, the 105706-HMC430LP4 offers identical RF performance with Sn/Pb finish and lower reflow temperature tolerance; versus HMC513LP5, it trades bandwidth and phase noise for smaller size, lower cost, and simpler layout-making it optimal for cost-sensitive, space-constrained C-band radios.

FAQ
What is the recommended PCB layout for 105706-HMC430LP4?
Per Hittite Application Note, the 105706-HMC430LP4 requires a 50 Ω RF trace from Pin 16 (RFOUT) with series DC-blocking capacitor, tight grounding of all GND pins and the exposed paddle using ≥8 thermal vias, and separate 4.7 μF + 10,000 pF bypassing on Pin 20 (Vcc). The evaluation board 105667 uses Rogers 4350 substrate and is available upon request.
Does 105706-HMC430LP4 require external tuning components?
No. The 105706-HMC430LP4 integrates the resonator, varactor, and buffer amplifier on a single GaAs die. No external inductors, capacitors, or resonators are needed-only DC blocking on RFOUT and proper bypassing on Vcc and VTUNE lines.
What is the maximum allowable tuning voltage for 105706-HMC430LP4?
The absolute maximum rating for VTUNE is +11 V. Operation above +10 V may cause frequency saturation or increased phase noise; the specified linear tuning range is 0–10 V, delivering full 5.0–5.5 GHz coverage.
Can 105706-HMC430LP4 operate below 3 V supply?
Yes-the 105706-HMC430LP4 functions down to 2.75 V (19 mA typical), though output power drops to +1 dBm and phase noise degrades by ~2 dB. Full specification compliance requires 3.0 V ±0.25 V per datasheet conditions.
Is 105706-HMC430LP4 pin-compatible with HMC430LP4E?
Yes-105706-HMC430LP4 and HMC430LP4E share identical pinout, footprint, and electrical specifications. The only differences are RoHS compliance (matte Sn vs. Sn/Pb) and peak reflow temperature (260 °C vs. 235 °C), making them drop-in replacements in compatible assembly processes.
