Product details
Overview
103802-HMC308 from Hittite Microwave Corporation (now part of Analog Devices) is a GaAs MMIC driver amplifier operating from 0.8 to 3.8 GHz, delivering 18 dB gain and +17 dBm P1dB output power at +5 V supply with 53 mA current draw. It functions as a broadband gain block or LO driver for passive mixers in compact RF front-ends.
For engineers reviewing the 103802-HMC308 datasheet, 103802-HMC308 pinout, 103802-HMC308 application, or 103802-HMC308 equivalent, key selection criteria include its SOT26 package, integrated DC blocking, single-supply operation (+3 V to +5 V), and verified performance across cellular, WLAN, and fixed wireless bands.
Technical Context
The 103802-HMC308 is a monolithic MESFET-based RF amplifier with fully integrated input/output DC blocking capacitors and 50 Ω matched ports. It requires no external matching components for basic broadband operation and supports bias tuning via single Vdd pin.
Its gain flatness (±2.5 dB over 0.8–3.8 GHz at +5 V), low gain variation (0.025–0.035 dB/°C), and stable P1dB (14–17 dBm across frequency bands) enable use in temperature-varying transmitter stages without recalibration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 0.8–3.8 GHz - Full-band operation without external tuning; usable as wideband driver or narrowband stage with external matching. |
| Small-Signal Gain | 18 dB @ +5 V - Enables single-stage amplification before power amplifiers or mixers in RF signal chains. |
| P1dB Output Power | +17 dBm @ +5 V - Sufficient drive level for LO injection into passive mixers or cascaded gain blocks. |
| Noise Figure | 7.0 dB @ +5 V - Acceptable for non-first-stage applications where gain precedes LNA in receiver paths. |
| Supply Current | 53 mA @ +5 V - Low quiescent power enables battery-sensitive or thermally constrained designs. |
| Input/Output Return Loss | 11 dB / 17 dB @ +5 V - Ensures >90% power transfer into/out of 50 Ω systems without external matching. |
| Output IP3 | +27 dBm @ +5 V - Supports moderate linearity requirements in multi-carrier or high-dynamic-range transmitters. |
Pinout & Package
SOT26 surface-mount package (2.9 mm × 2.8 mm × 1.3 mm), RoHS-compliant lead finish (100% matte Sn), MSL1 rating, and copper alloy leadframe. Ground pins require direct connection to PCB RF ground plane with multiple vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RFOUT | AC-coupled 50 Ω output; connects directly to next stage without external DC blocking. |
| 2, 5, 6 | GND | RF/DC ground terminals; must be soldered to solid ground plane for impedance stability and thermal dissipation. |
| 3 | Vdd | Single positive supply input (+3 V to +5 V); decoupling capacitor required near pin. |
| 4 | RFIN | AC-coupled 50 Ω input; accepts standard 50 Ω source without external DC blocking or matching. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated DC blocking | Eliminates need for external series capacitors on RFIN and RFOUT, reducing BOM count and board area. |
| Ultra-small footprint | 0.014 in² (9 mm²) SOT26 package enables dense RF module layouts in space-constrained radios. |
| Single-supply operation | Operates from +3 V or +5 V - simplifies power architecture and avoids dual-rail supplies in portable systems. |
| Thermal robustness | Rated for -40 °C to +85 °C operation with 160 °C/W channel-to-lead thermal resistance. |
| ESD protection | HBM Class 1A rating ensures handling safety during assembly without special ESD protocols beyond standard precautions. |
Applications
| Cellular/PCS Base Stations | WLAN 2.4/5 GHz Transceivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF driver amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC308E | RoHS-compliant variant with matte Sn finish and 260 °C peak reflow rating; identical electrical specs. | No functional difference; selected when lead-free assembly is required. | Direct replacement for 103802-HMC308 in RoHS-compliant manufacturing flows. |
| QPL9057 | Higher gain (20 dB), lower NF (3.5 dB), but narrower bandwidth (0.6–3.8 GHz) and +5 V only; no +3 V support. | Better suited for noise-sensitive receive-side gain blocks, not LO driver applications requiring +3 V flexibility. | Consider only when higher gain and lower noise outweigh loss of +3 V operation and broader 0.8–3.8 GHz flatness. |
Compared with 103802-HMC308, the HMC308E offers identical RF performance with RoHS compliance, while QPL9057 trades +3 V support and bandwidth flatness for improved gain and noise figure-making it suitable only for specific receive-chain roles.
