Product details
Overview
HMC387MS8E from Analog Devices (formerly Hittite Microwave) is a high-linearity GaAs MMIC passive mixer in an 8-lead MSOP package, designed for RF-to-IF downconversion and upconversion in 450–500 MHz cellular and land-mobile radio systems. It delivers +32 dBm input IP3 at +17 dBm LO drive, 9.5 dB typical conversion loss, and +22 dBm input P1dB - enabling robust signal handling without DC bias or external active components.
For engineers reviewing the HMC387MS8E datasheet, HMC387MS8E pinout, HMC387MS8E application, or HMC387MS8E equivalent, this device supports critical RF front-end design in GSM 450/480, CDMA 450, and private land mobile radio infrastructure where high dynamic range, small footprint (14.8 mm²), and LO drive flexibility (+13 to +19 dBm) are essential selection criteria.
Technical Context
The HMC387MS8E is a double-balanced passive mixer using GaAs Schottky diode quad topology, optimized for low-conversion-loss and high-isolation operation across its specified RF (450–500 MHz), LO (300–500 MHz), and IF (DC–150 MHz) bands. Its performance is stabilized over −40°C to +85°C with no DC bias required.
LO injection is AC-coupled via external L1/C1 network (e.g., 47 nH / 4 pF for 400 MHz), while RF and IF ports are DC-coupled - RF matched to 50 Ω across band, IF capable of DC operation up to ±40 mA. Thermal resistance is 175 °C/W with channel temperature rating up to 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 450–500 MHz - fully specified and characterized for GSM/CDMA 450–480 MHz base station and repeater applications. |
| Input IP3 (Typ.) | +32 dBm at +17 dBm LO - enables reception of strong interferers without distortion in high-density RF environments. |
| Conversion Loss | 9.5 dB typical - defines signal attenuation from RF to IF path; impacts receiver noise figure and gain budget. |
| LO Drive Range | +13 to +19 dBm - supports flexible LO source selection including lower-power synthesizers without performance penalty. |
| IF Bandwidth | DC–150 MHz - accommodates wideband IF architectures including 70 MHz, 97 MHz, 117 MHz, and 137 MHz plans. |
| LO–RF Isolation | 20 dB typical - reduces LO leakage into antenna path, easing filtering requirements in transceiver designs. |
| P1dB (Input) | +22 dBm - sets maximum undistorted RF input level before compression; critical for high-signal-strength base stations. |
Pinout & Package
Package: RoHS-compliant 8-lead MSOP (Mini Small Outline Package), body material = low-stress injection molded plastic, lead finish = 100% matte Sn, MSL1 rated, footprint area = 14.8 mm².
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | LO | AC-coupled 50 Ω input requiring external series inductor (L1) and shunt capacitor (C1) for impedance matching and frequency tuning. |
| 2, 4 | N/C | No internal connection; must remain unconnected per datasheet - not usable as grounds or test points. |
| 3, 6, 7 | GND | RF ground terminals - all three must be soldered directly to PCB ground plane with low-inductance connections to minimize noise and improve isolation. |
| 5 | IF | DC-coupled output; supports DC–150 MHz IF; requires external DC blocking if DC operation is not needed; max ±40 mA current limit. |
| 8 | RF | DC-coupled 50 Ω RF input port, matched across 450–500 MHz - no external matching required for nominal operation. |
Key Features
| Feature | Design Value |
|---|---|
| No DC bias required | Eliminates bias circuitry, reduces BOM count, improves reliability, and simplifies thermal design in compact RF modules. |
| +32 dBm input IP3 | Matches or exceeds performance of many active FET mixers while avoiding associated noise, power, and complexity penalties. |
| Ultra-small MSOP8 footprint (14.8 mm²) | Enables dense RF layout in space-constrained infrastructure equipment such as microcells and portable repeaters. |
| Wide LO drive range (+13 to +19 dBm) | Allows interoperability with diverse LO sources - from low-power PLLs to higher-output VCOs - without retuning. |
| DC–150 MHz IF bandwidth | Supports multiple standard IF frequencies (70/97/117/137 MHz) and baseband sampling in direct-conversion architectures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1040LP3E | Wider RF range (30–4000 MHz), higher conversion loss (10.5 dB typ), +29 dBm IP3, QFN-16 package. | Supports multiband infrastructure but lacks GSM 450–500 MHz optimization and MSOP8 size advantage. | Select when broad frequency coverage outweighs size and peak IP3 requirements. |
| ADL5801ACPZ-R7 | Active mixer, 10–6000 MHz RF, +24 dBm IP3, 8.2 dB conversion gain, 24-lead LFCSP, requires +5 V bias. | Provides gain instead of loss but adds power, heat, and complexity - unsuitable for zero-bias designs. | Select only when IF gain is mandatory and DC power is available; not a drop-in replacement. |
Compared with HMC387MS8E, HMC1040LP3E trades GSM-band optimization and compactness for wideband versatility, while ADL5801ACPZ-R7 introduces active gain and bias dependency - making HMC387MS8E uniquely suited for low-power, high-linearity, space-constrained 450–500 MHz infrastructure.

FAQ
What is the primary function of the HMC387MS8E in RF systems?
The HMC387MS8E is a passive double-balanced GaAs MMIC mixer used for frequency translation between RF (450–500 MHz) and IF (DC–150 MHz) bands in both downconversion and upconversion modes. It requires no DC bias, operates with +13 to +19 dBm LO drive, and delivers +32 dBm input IP3 - making it ideal for high-linearity infrastructure applications like GSM 450 base stations. The HMC387MS8E replaces bulkier active mixers while maintaining superior distortion performance.
Does the HMC387MS8E require external DC biasing?
No, the HMC387MS8E is a passive mixer and does not require any DC bias voltage or current. Its GaAs diode quad architecture operates solely on RF and LO signal energy, eliminating bias networks, reducing component count, and improving thermal stability. This feature is explicitly confirmed in the datasheet's General Description and Absolute Maximum Ratings sections, and applies identically to the HMC387MS8E variant.
What are the recommended external components for the LO port of the HMC387MS8E?
The LO port (Pin 1) of the HMC387MS8E requires an external series inductor (L1) and shunt capacitor (C1) to form an AC-coupled matching network. For 400 MHz LO operation, the datasheet specifies L1 = 47 nH and C1 = 4 pF - both placed as close as possible to Pin 1. These values scale with LO frequency ±10%; the HMC387MS8E's performance is validated only when this external network is correctly implemented per the application circuit.
How does the HMC387MS8E differ from the HMC387MS8?
The HMC387MS8E is the RoHS-compliant version of the HMC387MS8, differing only in package construction: HMC387MS8E uses 100% matte tin lead finish and RoHS-compliant low-stress plastic, with MSL1 rating and max reflow temperature of 260 °C, whereas HMC387MS8 uses Sn/Pb solder and max reflow of 235 °C. All electrical specifications, pinout, and performance data are identical between HMC387MS8E and HMC387MS8 - they are functionally interchangeable in new designs.
Can the HMC387MS8E be used for DC-coupled IF operation?
Yes, the IF port (Pin 5) of the HMC387MS8E is DC-coupled and supports operation from DC to 150 MHz. However, the device must not sink or source more than ±40 mA through this pin - exceeding that current risks permanent damage. For AC-coupled IF use, a series capacitor is required; for true DC-coupled IF, the connected circuit must stay within the ±40 mA absolute maximum rating at all times. This specification applies strictly to the HMC387MS8E as documented in the Pin Descriptions section.
