Product details
Overview
HMC358MS8G from Analog Devices (formerly Hittite Microwave) is a GaAs InGaP HBT monolithic voltage-controlled oscillator with integrated buffer amplifier, operating from 5.8 to 6.8 GHz. It delivers +11 dBm RF output power at 3 V supply, exhibits −110 dBc/Hz phase noise at 100 kHz offset, and requires no external resonator-enabling compact C-band transceiver designs for wireless infrastructure.
For engineers reviewing the HMC358MS8G datasheet, HMC358MS8G pinout, HMC358MS8G application, or HMC358MS8G equivalent, key selection criteria include its 5.8–6.8 GHz tuning range, 3V/100 mA operation, MSOP-8G package with exposed thermal paddle, and verified performance across −40°C to +85°C industrial temperature range.
Technical Context
The HMC358MS8G integrates resonators, negative resistance devices, varactor diodes, and a buffer amplifier on a single GaAs InGaP HBT die, eliminating discrete tuning components and reducing layout sensitivity. Its monolithic architecture ensures stable phase noise performance across temperature, shock, and process variation.
It operates from a single 3 V supply drawing 100 mA typical, with tuning voltage range of 0–10 V and output return loss ≥9 dB. Pulling is specified at 10 MHz peak-to-peak into 2.0:1 VSWR, and pushing is 150 MHz/V at Vtune = +3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 5.8–6.8 GHz - fully covers UNII-3 and C-band point-to-point radio bands. |
| Output Power | +11 dBm typical - sufficient to drive mixer LO ports or cascade into power amplifiers without external gain stages. |
| Phase Noise | −110 dBc/Hz @ 100 kHz offset - meets spectral purity requirements for 802.11a/HiperLAN WLAN receivers. |
| Supply Voltage | 3 V DC - compatible with standard low-voltage RF system rails; supports 2.75–3.25 V operation per characterization data. |
| Tuning Voltage Range | 0–10 V - enables wideband frequency modulation and PLL loop control using standard DACs or op-amp integrators. |
| Package | 8-lead MSOP-G (15 mm²) with exposed thermal paddle - requires RF and DC grounding of paddle and pins 4/5 for thermal stability and impedance control. |
| Operating Temp | −40°C to +85°C - qualified for outdoor wireless equipment and industrial-grade radio modules. |
Pinout & Package
Package: 8-lead MSOP-G (Moisture Sensitivity Level 1), low-stress molded plastic with exposed copper alloy thermal paddle. Dimensions per JEDEC MO-187 variant; all ground leads (pins 4, 5) and paddle must be soldered to PCB RF ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Vcc | DC supply input (3 V); bypass capacitor required close to pin for RF stability. |
| 2, 6, 7 | N/C | No internal connection; must remain unconnected and unstubbed in layout. |
| 3 | VTUNE | Control voltage input; high-impedance node sensitive to source impedance-requires low-Z drive for modulation fidelity. |
| 4, 5 | GND | RF and DC ground reference; must be directly tied to ground plane with multiple vias. |
| 8 | RFOUT | AC-coupled 50 Ω RF output; requires series DC-blocking capacitor before downstream stage. |
Key Features
| Feature | Design Value |
|---|---|
| No external resonator required | Monolithic integration eliminates discrete inductors/capacitors, reducing BOM count and layout sensitivity. |
| Integrated buffer amplifier | Isolates oscillator core from load variations, maintaining frequency stability under mismatch conditions. |
| Exposed thermal paddle | Enables direct conduction cooling to PCB ground plane, sustaining +11 dBm output over full temperature range. |
| Low phase noise over temperature | −110 dBc/Hz @ 100 kHz maintained from −40°C to +85°C-critical for coherent C-band demodulation. |
| Single 3 V supply operation | Eliminates need for dual-rail or charge-pump supplies, simplifying power delivery in compact radios. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar VCO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC513LP5 | Wider 4.8–6.0 GHz range; higher +13 dBm output; 32-lead QFN package; requires external matching. | Better suited for multi-band systems needing extended lower-frequency coverage and higher drive capability. | Select HMC513LP5 when >+12 dBm output or sub-5.8 GHz support is required; not drop-in due to different package and biasing. |
| MAX2752 | 5.15–5.825 GHz range; integrated PLL; 24-pin TQFN; 2.7–3.6 V supply; lower −105 dBc/Hz phase noise @ 100 kHz. | Targets integrated transceivers where PLL-on-chip reduces component count but sacrifices tuning linearity. | Choose MAX2752 for fully integrated PLL+VCO solutions in space-constrained 802.11n designs; HMC358MS8G offers superior phase noise and analog tuning flexibility. |
Compared with HMC513LP5 and MAX2752, the HMC358MS8G provides optimal balance of phase noise, tuning linearity, and board-level simplicity for fixed-band C-band radios-without requiring external matching networks or sacrificing analog control precision.

FAQ
What is the recommended PCB layout practice for the HMC358MS8G?
Ground pins 4 and 5 plus the exposed thermal paddle must be soldered directly to a solid RF ground plane using multiple thermal vias. The RFOUT trace must be 50 Ω microstrip, AC-coupled with a series capacitor, and isolated from noisy digital traces. Vcc requires local 10 μF tantalum + 100 nF ceramic bypassing near pin 1.
Does the HMC358MS8G require external tuning components?
No-the HMC358MS8G integrates all resonant and active elements monolithically. No external inductors, capacitors, or varactors are needed for basic VCO operation. Only passive bypassing, coupling, and grounding components are required per the evaluation board design.
What is the maximum allowable tuning voltage for the HMC358MS8G?
The absolute maximum rating for VTUNE is 11 V DC. Operation above 10 V is outside the specified tuning range and may cause frequency saturation or increased phase noise. For reliable linear tuning, keep VTUNE between 0 V and 10 V as characterized in the datasheet.
How does the HMC358MS8G perform under temperature variation?
The HMC358MS8G maintains −110 dBc/Hz phase noise at 100 kHz offset from −40°C to +85°C. Frequency drift is 0.8 MHz/°C, and output power varies less than ±0.5 dB across that range-verified by test data in Figures 11-3 and 11-4 of the datasheet.
Is the HMC358MS8G RoHS-compliant?
The HMC358MS8G uses Sn/Pb lead finish and is not RoHS-compliant. For RoHS compliance, use the HMC358MS8GE variant, which features 100% matte tin plating and MSL1 rating with 260 °C peak reflow tolerance.
