Product details
Overview
105706-HMC386LP4 from Analog Devices (formerly Hittite Microwave) is a GaAs InGaP HBT MMIC voltage-controlled oscillator with integrated buffer amplifier, operating from 2.6 to 2.8 GHz, delivering +5 dBm output power at 3 V/35 mA, and achieving −114 dBc/Hz phase noise at 100 kHz offset - used in wireless infrastructure RF front-ends requiring stable, low-noise local oscillation.
For engineers reviewing the 105706-HMC386LP4 datasheet, 105706-HMC386LP4 pinout, 105706-HMC386LP4 application, or 105706-HMC386LP4 equivalent, key selection criteria include tuning voltage range (0–10 V), pulling tolerance (3 MHz pp into 2.0:1 VSWR), pushing sensitivity (2 MHz/V), frequency drift rate (0.3 MHz/°C), and QFN-24 package thermal resistance (138 °C/W).
Technical Context
The 105706-HMC386LP4 integrates monolithic resonator, negative resistance device, varactor diode, and buffer amplifier on a single GaAs die, eliminating external resonator requirements. Its HBT process ensures robust phase noise performance across −40°C to +85°C and under mechanical stress.
It operates from a single 3 V supply with 35 mA typical current draw, features a 24-pin 4×4 mm QFN package with exposed paddle for RF/DC grounding, and supports modulation via VTUNE (pin 22) with bandwidth dependent on source impedance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar VCO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC386LP4E | RoHS-compliant; matte Sn finish; 260 °C max reflow vs. 235 °C for HMC386LP4 | Same electrical specs and pinout; intended for lead-free assembly lines | Select HMC386LP4E when RoHS compliance and higher reflow profile are required |
| MAX2752 | Si-based; 2.4–2.5 GHz range; −105 dBc/Hz phase noise @ 100 kHz; 20-pin QFN | Narrower band; lower phase noise margin; optimized for Bluetooth/Wi-Fi SoC integration | Choose MAX2752 only for cost-sensitive 2.4 GHz ISM-band designs where −9 dBc/Hz phase noise degradation is acceptable |
Compared with HMC386LP4E, the 105706-HMC386LP4 offers identical RF performance but requires Sn/Pb soldering; versus MAX2752, it delivers superior phase noise and wider tuning range at the cost of process technology and frequency coverage.

FAQ
What is the absolute maximum tuning voltage for the 105706-HMC386LP4?
The absolute maximum tuning voltage for the 105706-HMC386LP4 is +11 V, as specified in the Absolute Maximum Ratings table. Exceeding this voltage may cause permanent damage to the internal varactor diode. Operation within the recommended 0–10 V range ensures reliable performance and longevity of the 105706-HMC386LP4 across its full temperature range.
Does the 105706-HMC386LP4 require external matching networks at the RF output?
Yes, the 105706-HMC386LP4 has an output return loss of 9 dB, indicating only moderate 50 Ω match. For optimal power transfer and harmonic suppression, a simple external matching network - typically a series inductor and shunt capacitor - is recommended before connecting to mixers or filters. The 105706-HMC386LP4 evaluation board (105667) provides a validated reference layout.
Can the 105706-HMC386LP4 operate from a 2.7 V supply?
Yes, the 105706-HMC386LP4 is rated for Vcc from 2.75 V to 3.5 V. At 2.7 V, typical supply current drops to 30 mA and output power remains within specification (≥2 dBm). This makes the 105706-HMC386LP4 suitable for brown-out tolerant systems where rail voltage may dip temporarily without disrupting RF functionality.
What is the thermal resistance (RTH) of the 105706-HMC386LP4 package?
The thermal resistance (junction-to-package base) of the 105706-HMC386LP4 is 138 °C/W. This value assumes proper soldering of all ground leads and the exposed paddle to a multilayer PCB ground plane with ≥6 thermal vias. Maintaining this thermal path is essential to keep junction temperature below 135 °C under continuous 35 mA operation - a key reliability factor for the 105706-HMC386LP4 in enclosed enclosures.
Is the 105706-HMC386LP4 pin-compatible with the HMC386LP4E variant?
Yes, the 105706-HMC386LP4 is mechanically and electrically pin-compatible with the HMC386LP4E. Both share identical 24-pin QFN footprint, pin functions, and electrical specifications. The only differences are RoHS compliance, lead finish (Sn/Pb vs. matte Sn), and maximum reflow temperature (235 °C vs. 260 °C). No PCB redesign is needed when substituting the 105706-HMC386LP4 for HMC386LP4E in existing layouts.
