Product details
Overview
HMC387MS8TR from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC passive double-balanced mixer for RF downconversion and upconversion in 450–500 MHz cellular and land mobile radio systems. It delivers +32 dBm input IP3, 9.5 dB typical conversion loss, and +22 dBm input P1dB at +17 dBm LO drive, operating with DC–150 MHz IF bandwidth and no DC bias requirement.
For engineers reviewing the HMC387MS8TR datasheet, HMC387MS8TR pinout, HMC387MS8TR application, or HMC387MS8TR equivalent, this device is selected for high-dynamic-range receiver front-ends, GSM/CDMA 450–480 MHz base stations, and private land mobile radio transceivers where low external part count and ultra-small MSOP8 footprint are critical.
Technical Context
This passive mixer uses a GaAs Schottky diode-based double-balanced architecture optimized for high linearity and wide IF bandwidth. Its RF and LO ports are internally matched to 50 Ω across 450–500 MHz and 300–500 MHz respectively, while the IF port supports DC-coupled operation up to 150 MHz with ±40 mA current tolerance.
Performance is specified at TA = +25°C with LO drive between +13 dBm and +19 dBm; it maintains +30 dBm IP3 even at +13 dBm LO, enabling flexible LO source selection. Thermal resistance is 175 °C/W, supporting operation from –40°C to +85°C with channel temperature limited to 150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 450–500 MHz - fully specified band for RF port matching and conversion performance |
| LO Frequency Range | 300–500 MHz - supports low-side injection with external L1/C1 tuning for optimal isolation |
| IF Frequency Range | DC–150 MHz - enables direct-coupled IF interfaces including zero-IF and low-IF architectures |
| Input IP3 | +32 dBm (typ.) - ensures minimal intermodulation distortion in dense signal environments like GSM 450 base stations |
| Conversion Loss | 9.5 dB (typ.) - defines signal attenuation from RF to IF path; impacts system noise figure budget |
| LO–RF Isolation | 20 dB (typ.) - reduces LO leakage into antenna path, easing filtering requirements in transmit chains |
| P1dB (Input) | +22 dBm - sets maximum undistorted RF input level before compression degrades dynamic range |
Pinout & Package
Package: MSOP8 (Mini Small Outline Package), 3.0 × 3.0 × 0.85 mm, 14.8 mm² footprint, RoHS-compliant matte Sn finish (MSL1, 260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | LO | AC-coupled 50 Ω input requiring external series inductor (L1) and shunt capacitor (C1) for impedance match |
| 2, 4 | N/C | No internal connection; must remain unconnected per design |
| 3, 6, 7 | GND | RF ground terminals - require low-inductance soldering to PCB ground plane for isolation and thermal dissipation |
| 5 | IF | DC-coupled output; supports DC–150 MHz IF; max ±40 mA DC current to avoid damage |
| 8 | RF | DC-coupled 50 Ω RF input matched across 450–500 MHz; accepts +22 dBm P1dB signal |
Key Features
| Feature | Design Value |

| +32 dBm input IP3 | Enables coexistence with strong interferers in multi-channel infrastructure without active linearization |
| Ultra-small MSOP8 package | 14.8 mm² footprint saves board space vs. larger SOIC or QFN mixers in compact radio modules |
| DC–150 MHz IF bandwidth | Supports both zero-IF receivers and traditional 70/137 MHz IF plans without external AC coupling |
| +13 dBm minimum LO drive | Reduces LO amplifier output power requirement, lowering system power consumption and heat generation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC387MS8E | RoHS-compliant version with 100% matte Sn lead finish and 260°C MSL1 reflow rating; identical electrical specs | Required for lead-free manufacturing; same PCB layout and thermal profile as HMC387MS8TR | Select HMC387MS8E when RoHS compliance and Pb-free assembly are mandatory. |
| ADL5801ACPZ-R7 | Active mixer with +26 dBm IP3, 7.8 dB conversion gain, 5 V supply, and 700–2700 MHz RF range | Requires DC bias and generates higher noise figure; suited for wider-band, gain-sensitive designs | Choose ADL5801ACPZ-R7 only if system requires conversion gain and broader RF bandwidth beyond 500 MHz. |
Compared with HMC387MS8TR, HMC387MS8E offers identical RF performance with RoHS compliance, while ADL5801ACPZ-R7 trades passive simplicity for active gain and wider frequency coverage-making HMC387MS8TR optimal for cost-sensitive, low-power, high-IP3 450–500 MHz infrastructure.

FAQ
What is the recommended LO drive level for optimal IP3 performance of the HMC387MS8TR?
The HMC387MS8TR achieves its maximum +32 dBm input IP3 at +17 dBm LO drive, but maintains +30 dBm IP3 even at +13 dBm LO. This flexibility allows use with lower-power LO sources while preserving linearity-critical for battery-powered PLMR radios. The HMC387MS8TR datasheet specifies LO drive range as +13 to +19 dBm for full parameter compliance.
Does the HMC387MS8TR require external DC blocking capacitors on its RF or IF ports?
The RF port of the HMC387MS8TR is DC-coupled and matched to 50 Ω from 450–500 MHz, so no DC blocking is needed unless DC voltage is present on the RF source. The IF port is also DC-coupled but must not sink/source more than ±40 mA; for non-DC applications, an external series capacitor is required. The HMC387MS8TR does not integrate internal DC blocking.
Can the HMC387MS8TR be used for upconversion, and what is its upconverter IP3?
Yes, the HMC387MS8TR supports bidirectional operation: as a downconverter (RF→IF) and upconverter (IF→RF). Its upconverter input IP3 is +29 dBm (typ.) at +17 dBm LO drive and 70 MHz IF, verified per the HMC387MS8TR electrical specifications table. This makes it suitable for GSM 450 transmit paths where LO–RF isolation exceeds 17 dB.
What external components are required to interface the LO port of the HMC387MS8TR?
The LO port (Pin 1) of the HMC387MS8TR requires an external series inductor (L1) and shunt capacitor (C1) to form a matching network. For 400 MHz LO, the recommended values are 47 nH (0805 inductor) and 4 pF (0603 capacitor). These components must be placed as close as possible to Pin 1 to minimize parasitic inductance-no internal LO matching is provided in the HMC387MS8TR die.
Is the HMC387MS8TR pin-compatible with the HMC387MS8E variant?
Yes, the HMC387MS8TR and HMC387MS8E share identical pinout, package dimensions, and electrical specifications. The only differences are lead finish (Sn/Pb vs. 100% matte Sn) and MSL rating (235°C vs. 260°C peak reflow). No PCB layout changes are required when substituting HMC387MS8TR with HMC387MS8E in RoHS-compliant assemblies.
