Product details
Overview
105706-HMC532LP4 from Analog Devices (formerly Hittite Microwave) is a GaAs InGaP HBT MMIC voltage-controlled oscillator with integrated buffer amplifier, operating from 7.1 to 7.9 GHz, delivering +14 dBm output power at +3 V/85 mA, with -103 dBc/Hz phase noise at 100 kHz offset, used in VSAT and point-to-point radio transceivers.
For engineers reviewing the 105706-HMC532LP4 datasheet, 105706-HMC532LP4 pinout, 105706-HMC532LP4 application, or 105706-HMC532LP4 equivalent, key selection criteria include tuning voltage range (1–13 V), pulling sensitivity (28 MHz pp into 2.0:1 VSWR), pushing (78 MHz/V), frequency drift (0.85 MHz/°C), and RFOUT AC-coupled output interface.
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 delivers stable oscillation across -40°C to +85°C with minimal sensitivity to supply variation (78 MHz/V pushing) and load mismatch (28 MHz pp pulling).
Phase noise performance is optimized via monolithic construction and internal buffering, achieving -101 dBc/Hz typical at 100 kHz offset under +3 V bias and +5 V tune voltage. Output return loss exceeds 15 dB, and harmonic suppression reaches -14 dBc (2nd) and -25 dBc (3rd).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar VCO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC532LP4E | RoHS-compliant variant with 100% matte Sn finish and 260°C reflow rating; identical electrical specs | Required for lead-free manufacturing; same thermal and RF performance | Select HMC532LP4E when RoHS compliance or higher reflow temperature is mandated |
| HMC513LP5 | Wider 5.8–6.8 GHz range, +13 dBm output, -100 dBc/Hz phase noise @ 100 kHz, 5×5 mm QFN | Lower-frequency alternative for C-band systems; larger footprint and different tuning slope | Choose HMC513LP5 only when 5.8–6.8 GHz coverage is required and board space allows 5×5 mm package |
Compared with HMC532LP4E, the 105706-HMC532LP4 offers identical RF performance but lacks RoHS compliance; versus HMC513LP5, it provides higher frequency coverage and tighter package size at the cost of reduced low-band flexibility.

FAQ
What is the operating temperature range for the 105706-HMC532LP4?
The 105706-HMC532LP4 operates from -40°C to +85°C ambient temperature. Its monolithic GaAs construction ensures stable phase noise and frequency drift (0.85 MHz/°C) across this range. The device's channel temperature must not exceed 135°C, and thermal resistance from junction to ground paddle is 165 °C/W. Proper PCB grounding and thermal vias are essential to maintain reliability at maximum ambient conditions.
Does the 105706-HMC532LP4 require external tuning components?
No, the 105706-HMC532LP4 does not require external resonators or tuning capacitors. It integrates the resonator, varactor diode, negative resistance device, and buffer amplifier on a single GaAs die. This monolithic design eliminates discrete LC tank components, reduces board space, and improves repeatability and temperature stability - all confirmed in the functional diagram and general description of the 105706-HMC532LP4 datasheet.
What is the recommended power supply decoupling for the 105706-HMC532LP4?
The 105706-HMC532LP4 requires dual-stage decoupling on the Vcc pin (pin 20): a 4.7 μF tantalum capacitor and a 10,000 pF ceramic capacitor in parallel, placed as close as possible to the package. This configuration suppresses low- and high-frequency supply noise, ensuring stable oscillation and minimizing pushing effects. The evaluation PCB (105667) implements this exact layout, and the datasheet specifies 85 mA supply current at +3 V.
How is the RF output of the 105706-HMC532LP4 interfaced?
The RF output (pin 16) of the 105706-HMC532LP4 is AC-coupled and designed for 50 Ω systems. An external DC-blocking capacitor must be placed in series between pin 16 and the load (e.g., mixer LO port). The datasheet specifies >15 dB output return loss, confirming good 50 Ω match. Grounding of the exposed paddle and all ground pins is mandatory to preserve RF performance and minimize radiation losses.
What is the absolute maximum tuning voltage for the 105706-HMC532LP4?
The absolute maximum tuning voltage (Vtune) for the 105706-HMC532LP4 is +15 V, as specified in the Absolute Maximum Ratings table. Operation beyond this voltage risks permanent damage to the integrated varactor diode. The functional tuning range is 1–13 V, delivering full 7.1–7.9 GHz coverage. Exceeding 13 V yields no additional frequency range and increases leakage current risk above the 10 μA typical spec.
