Product details
Overview
HMC474MP86 from Analog Devices (formerly Hittite Microwave) is a SiGe HBT monolithic microwave integrated circuit (MMIC) gain block amplifier operating from DC to 6 GHz, delivering 15.5 dB small-signal gain, +8 dBm P1dB output power, and +22 dBm OIP3 at 850 MHz with 25 mA supply current from a single +5 V supply. It serves as a cascadable 50 Ω RF/IF gain stage in cellular base stations and microwave test equipment.
For engineers reviewing the HMC474MP86 datasheet, HMC474MP86 pinout, HMC474MP86 application, or HMC474MP86 equivalent, this page provides verified technical context, package mapping, real-world use scenarios, and validated alternative options for RF front-end design and broadband signal chain optimization.
Technical Context
The HMC474MP86 employs a Darlington feedback pair architecture using SiGe HBT technology, enabling stable gain over temperature (±0.015 dB/°C) and reduced sensitivity to process variation. Its DC-coupled RFIN and RFOUT pins require external blocking capacitors, and bias is applied via RFOUT through an external resistor (e.g., 110 Ω at +5 V).
It operates across –40°C to +85°C with 50 Ω input/output impedance, supports single-supply voltages from +3 V to +10 V, and achieves 3.0 dB noise figure up to 5 GHz. Reverse isolation exceeds 17 dB below 4 GHz, supporting robust cascaded multi-stage designs without oscillation risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | DC to 6 GHz - enables wideband IF and RF gain in transceivers and spectrum analyzers. |
| Small-Signal Gain | 15.5 dB typical at 850 MHz - provides sufficient cascade margin before compression in multi-stage amplifiers. |
| P1dB Output Power | +8 dBm at 0.5–4 GHz - supports linearity-critical stages in PCS and WLAN uplinks. |
| OIP3 | +22 dBm at 850 MHz - ensures low intermodulation distortion in multi-carrier cellular infrastructure. |
| Noise Figure | 3.0 dB up to 5 GHz - suitable for low-noise pre-amplification ahead of mixers or ADCs. |
| Supply Current | 25 mA at +5 V - enables low-power operation while maintaining RF performance across temperature. |
| Input/Output Impedance | 50 Ω - simplifies integration into standard RF PCB layouts without matching networks. |
Pinout & Package
The HMC474MP86 uses the Micro-P surface-mount package (dimensionally compatible with Micro-X), with Sn/Pb lead finish and MSL1 rating. Leadframe is copper alloy; all ground leads must be soldered directly to PCB RF ground per layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RFIN | DC-coupled RF input requiring external blocking capacitor; matched to 50 Ω system impedance. |
| 2, 4 | GND | RF and DC ground terminals; must connect directly to solid ground plane with multiple vias for minimal inductance. |
| 3 | RFOUT | RF output and DC bias feed point; supplies collector voltage to internal transistor stages via external bias resistor. |
Key Features
| Feature | Design Value |
|---|---|
| Darlington feedback pair topology | Delivers ±0.015 dB/°C gain stability and reduced process sensitivity versus single-transistor MMICs. |
| Cascadable 50 Ω I/O | Enables direct connection between stages without impedance-matching components in broadband systems. |
| Single positive supply range (+3 V to +10 V) | Supports flexible biasing in mixed-voltage RF subsystems without negative rails or charge pumps. |
| ESD rating Class 1B (HBM) | Requires handling per ESD-sensitive device protocols but allows integration into automated SMT lines with proper controls. |
| Operating temperature range (–40°C to +85°C) | Validated for deployment in outdoor wireless infrastructure and industrial test equipment enclosures. |
Applications
| Cellular Base Station Receiver Chain | WLAN 2.4/5 GHz Front-End |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF gain block applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC476MS8G | Higher gain (20 dB), narrower bandwidth (DC–4 GHz), +11 dBm P1dB, requires dual supply (Vcc/Vee). | Better suited for low-frequency, high-gain IF chains where bandwidth beyond 4 GHz is unnecessary. | Select when higher gain and lower noise (2.5 dB NF) outweigh need for 6 GHz coverage and single-supply simplicity. |
| QPL9547 | 5 GHz max frequency, +16 dBm P1dB, 0.5 dB NF, 50 Ω I/O, +5 V single supply, GaAs pHEMT process. | Optimized for ultra-low-noise 5G FR1 receiver paths; not rated above 5 GHz or for DC coupling. | Prefer for sub-6 GHz 5G NR user equipment where noise figure dominates over bandwidth and DC coupling requirements. |
Compared with HMC474MP86, HMC476MS8G trades bandwidth and supply simplicity for higher gain and lower noise in narrowband IF roles, while QPL9547 offers superior noise performance below 5 GHz but lacks DC coupling and 6 GHz reach-making HMC474MP86 uniquely balanced for wideband, single-supply, cascadable gain in infrastructure and test gear.

FAQ
What is the recommended bias resistor value for HMC474MP86 at +5 V supply?
The recommended bias resistor (RBIAS) for HMC474MP86 at +5 V supply is 110 Ω, calculated as (Vs − Vcc)/Icc = (5 V − 2.4 V)/25 mA. This value ensures stable 25 mA collector current across temperature and maintains +8 dBm P1dB performance. Use a 1/8 W rated resistor and confirm thermal derating in high-density layouts.
Does HMC474MP86 require external DC blocking capacitors?
Yes, HMC474MP86 requires external DC blocking capacitors on both RFIN (Pin 1) and RFOUT (Pin 3) because its inputs and outputs are DC-coupled. Typical values are 100 pF at 900 MHz and 0.01 μF at 50 MHz, selected per application frequency to maintain 50 Ω impedance and avoid resonance near band edges.
What is the maximum junction temperature and thermal resistance of HMC474MP86?
HMC474MP86 has a maximum junction temperature of 150 °C and a thermal resistance (junction-to-lead) of 232 °C/W. At 85 °C case temperature, its continuous power dissipation is 0.280 W, derating by 4.3 mW/°C above that. Proper PCB grounding and thermal vias are mandatory to sustain full RF performance under continuous operation.
Is HMC474MP86 RoHS-compliant?
The HMC474MP86 is not RoHS-compliant; it uses Sn/Pb solder finish and is rated MSL1 with a peak reflow temperature of 235 °C. For RoHS compliance, use the pin-compatible HMC474MP86E variant, which features 100% matte tin plating and 260 °C reflow tolerance.
Can HMC474MP86 operate with supply voltages other than +5 V?
Yes, HMC474MP86 supports single positive supply voltages from +3 V to +10 V. At +3 V, RBIAS = 30 Ω yields 25 mA; at +10 V, RBIAS = 300 Ω is required. Gain remains stable across this range, but P1dB and OIP3 improve slightly with higher Vcc-e.g., +9 dBm P1dB at +8 V versus +8 dBm at +5 V.
