Product details
Overview
HMC387MS8 from Analog Devices (formerly Hittite Microwave) is a high-dynamic-range GaAs MMIC passive 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 HMC387MS8 datasheet, HMC387MS8 pinout, HMC387MS8 application, or HMC387MS8 equivalent, this device supports critical RF front-end design in GSM 450/480, CDMA 450, and private land mobile radio infrastructure where high linearity, small footprint (14.8 mm² MSOP8), and low external part count are essential.
Technical Context
The HMC387MS8 is a passive double-balanced mixer using GaAs Schottky diode quad topology, optimized for low-side LO injection and broadband RF port matching from 450–500 MHz. Its RF and IF ports are DC-coupled, while the LO port requires external AC coupling via series inductor (L1) and shunt capacitor (C1) tuned to the target LO frequency range (300–500 MHz).
It achieves >20 dB LO-to-RF and LO-to-IF isolation, 9.5 dB noise figure (SSB), and maintains +30 dBm input IP3 even at reduced +13 dBm LO drive-enabling flexible LO power sourcing without active bias circuitry or thermal management overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 450–500 MHz: Fully specified match and performance across entire band for GSM/CDMA base station receive paths. |
| LO Frequency Range | 300–500 MHz: Supports low-side injection configurations; external L1/C1 tuning required per LO frequency ±10%. |
| IF Frequency Range | DC–150 MHz: Enables direct-baseband or low-IF architectures without external DC blocking on IF port. |
| Input IP3 (Typ.) | +32 dBm @ +17 dBm LO: Delivers high linearity for multi-carrier reception in congested spectrum environments. |
| Conversion Loss | 9.5 dB (typ.): Predictable signal attenuation enables accurate gain budgeting without active amplification in IF chain. |
| Input P1dB | +22 dBm (typ.): Supports strong interferer rejection before compression in receiver front ends. |
| Noise Figure (SSB) | 9.5 dB (typ.): Defines system sensitivity floor when cascaded with LNA; consistent with passive mixer trade-offs. |
Pinout & Package
Package: MSOP8 (Mini Small Outline Package), 14.8 mm² footprint, Sn/Pb lead finish, MSL1 rating, thermal resistance 175 °C/W. All ground pins (3, 6, 7) must be soldered directly to PCB RF ground plane with multiple vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | LO | AC-coupled LO input requiring external series inductor (L1) and shunt capacitor (C1); matched to 50 Ω at target LO frequency. |
| 2, 4 | N/C | No internal connection; must remain unconnected and unstubbed on PCB layout. |
| 3, 6, 7 | GND | RF ground terminals; require low-inductance soldering to solid ground plane for optimal isolation and IP3 performance. |
| 5 | IF | DC-coupled output; supports DC–150 MHz IF; current-limited to ±40 mA; external DC blocking cap needed if DC not required. |
| 8 | RF | DC-coupled RF input; internally matched to 50 Ω across 450–500 MHz; accepts +25 dBm max input (absolute rating). |
Key Features
| Feature | Design Value |
|---|---|
| No DC bias required | Eliminates bias network complexity, leakage paths, and thermal drift-reducing BOM count and improving reliability in unattended infrastructure. |
| +32 dBm input IP3 | Enables coexistence with strong adjacent-channel signals in GSM 450/CDMA 450 base stations without desensitization. |
| Ultra-small MSOP8 package | 14.8 mm² footprint saves board space vs. larger SOIC or QFN mixers-critical for compact remote radio heads and repeaters. |
| DC–150 MHz IF bandwidth | Supports zero-IF and low-IF receiver architectures without external IF filtering or AC coupling components. |
| +13 to +19 dBm LO drive range | Accommodates diverse LO sources (VCOs, synthesizers, buffers) without level-shifting circuitry or power amplifiers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP3E | Wider RF range (400–6000 MHz), higher conversion loss (11.5 dB typ.), +27 dBm IP3, 16-pin QFN package. | Supports multi-band infrastructure but lacks DC-coupled IF and requires more board area. | Choose for wideband test equipment or multi-standard radios where 450–500 MHz is one of many bands. |
| ADL5801ACPZ-R7 | Active mixer; 10–6000 MHz RF, +24 dBm IP3, 8.2 dB conversion gain, requires +5 V/60 mA bias. | Provides gain instead of loss but adds power, heat, and noise; unsuitable for ultra-low-power or thermally constrained designs. | Choose only when system-level gain budget demands active conversion and DC power is available. |
Compared with HMC1048LP3E and ADL5801ACPZ-R7, the HMC387MS8 uniquely balances narrowband 450–500 MHz optimization, passive operation, DC-coupled IF, and ultra-compact MSOP8 packaging-making it the most efficient solution for dedicated GSM/CDMA 450 infrastructure front ends.

FAQ
What is the recommended LO drive level for optimal performance of the HMC387MS8?
The HMC387MS8 achieves its best linearity (+32 dBm input IP3) at +17 dBm LO drive, but maintains +30 dBm IP3 down to +13 dBm LO. This wide LO drive range allows flexibility with VCOs or buffer amplifiers. Operating outside +13 to +19 dBm may degrade conversion loss or increase distortion. The HMC387MS8 datasheet specifies all electrical characteristics at +17 dBm unless otherwise noted.
Can the HMC387MS8 be used for upconversion applications?
Yes, the HMC387MS8 supports bidirectional operation: it functions as both a downconverter (RF→IF) and upconverter (IF→RF). Its upconverter input IP3 is +29 dBm at +17 dBm LO drive, making it suitable for low-power transmit paths in repeaters and PLMR transceivers. The HMC387MS8 maintains consistent RF port matching and isolation specs in either mode.
Is DC coupling on the IF port mandatory for the HMC387MS8?
No, DC coupling is inherent but not mandatory. Pin 5 (IF) is DC-coupled and supports DC–150 MHz operation, but if DC response is unnecessary, an external series capacitor can block DC while preserving IF bandwidth. However, the HMC387MS8 must not sink or source more than ±40 mA through this pin-exceeding that risks damage.
What external components are required for proper LO interface with the HMC387MS8?
The HMC387MS8 LO port (Pin 1) requires external AC coupling: a series inductor (L1) and shunt capacitor (C1) tuned to the target LO frequency. 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 preserve impedance match and minimize parasitic effects in the HMC387MS8 application circuit.
Does the HMC387MS8 require thermal management in typical operation?
Under standard conditions (+17 dBm LO, +0 dBm RF input), the HMC387MS8 dissipates minimal power and operates within its -40°C to +85°C case temperature range without heatsinking. Its thermal resistance is 175 °C/W, so ambient temperatures ≤+70°C with adequate PCB copper pour on ground pins (3, 6, 7) are sufficient. The HMC387MS8 absolute max channel temperature is 150°C-exceeding this voids reliability.
