Product details
Overview
HMC187AMS8 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC passive frequency doubler in an 8-lead MSOP package, operating with 0.85–2.0 GHz input and delivering 1.7–4.0 GHz output. It achieves 15 dB typical conversion loss at +15 dBm drive, provides ≥40 dB fundamental/3rd/4th harmonic isolation, and is DC-coupled with 50 Ω matched RF ports for wireless local loop and point-to-point radio transceivers.
For engineers reviewing the HMC187AMS8 datasheet, HMC187AMS8 pinout, HMC187AMS8 application, or HMC187AMS8 equivalent, key selection criteria include its passive Schottky diode architecture, temperature-stable conversion gain across –40°C to +85°C, no additive phase noise, and requirement for external grounding of N/C pins to RF ground.
Technical Context
The HMC187AMS8 implements a balanced passive doubler using GaAs Schottky diode and integrated balun topology, enabling harmonic suppression without active biasing. Its operation relies on nonlinear current-voltage characteristics of the diode pair, with input and output ports both DC-coupled and impedance-matched to 50 Ω.
Performance is drive-level dependent: conversion loss improves from 18 dB (min) at +10 dBm to 15 dB (typ) at +20 dBm, while FO, 3FO, and 4FO isolation remain ≥35 dB, ≥42 dB, and ≥30 dB respectively across the full input band and temperature range (–40°C to +85°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Frequency Range | 0.85–2.0 GHz: supports U-NII, LMDS, and VSAT bands with single-device doubling |
| Output Frequency Range | 1.7–4.0 GHz: delivers doubled spectrum without external filtering for many 2.4/3.5/5.8 GHz systems |
| Conversion Loss | 15 dB typ @ +15 dBm: defines RF power budget penalty when cascading with LNAs or drivers |
| FO Isolation | ≥45 dB typ @ +15 dBm: minimizes fundamental feedthrough into downstream mixers or filters |
| 3FO/4FO Isolation | ≥46 dB / ≥40 dB typ @ +15 dBm: reduces need for post-doubler harmonic suppression stages |
| Operating Temp | –40°C to +85°C: validated performance across industrial and outdoor wireless equipment environments |
| Input Drive Level | +10 to +20 dBm: requires driver stage capable of stable high-power output without compression |

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive frequency doubler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC575LP3E | Wider input range (0.5–3.0 GHz), higher drive (+23 dBm max), 3× smaller 3 mm × 3 mm QFN package | Better suited for compact SMT designs requiring broader bandwidth and higher power handling | Select when board space is constrained and input drive exceeds +20 dBm |
| Qorvo QM11036 | 0.7–2.7 GHz input, 13.5 dB typ conversion loss at +17 dBm, GaN-on-SiC process, +105°C max operating temp | Targeted for harsh-environment military/aerospace systems requiring extended temperature margin | Select when operation beyond +85°C or higher reliability under thermal cycling is required |
Compared with HMC187AMS8, HMC575LP3E offers wider bandwidth and smaller footprint but requires re-layout; QM11036 delivers superior thermal robustness and lower loss but at higher cost and different process technology-neither is pin-compatible, and both demand updated matching network design.

FAQ
What is the recommended input drive level for optimal conversion loss in the HMC187AMS8?
The HMC187AMS8 achieves minimum conversion loss (15 dB typical) at +15 dBm to +20 dBm input drive. Below +10 dBm, conversion loss degrades significantly (>18 dB), and above +20 dBm risks exceeding the +27 dBm absolute maximum rating. For stable operation in production systems, +15 dBm is the preferred nominal drive level for HMC187AMS8.
Does the HMC187AMS8 require DC biasing or external power supply?
No, the HMC187AMS8 is a fully passive GaAs Schottky diode-based frequency doubler and requires no DC bias voltage or current. It operates solely on the RF input signal. All pins either connect to RF/DC ground (pins 1, 4, 5, 8, 3, 6) or serve as DC-coupled RF ports (pin 2 RFIN, pin 7 RFOUT). No external power supply is needed for HMC187AMS8 functionality.
How should the N/C pins (1, 4, 5, 8) of the HMC187AMS8 be handled on the PCB?
Pins 1, 4, 5, and 8 are internally unconnected but must be externally tied to the PCB's RF/DC ground plane using low-inductance vias or traces. This grounding is mandatory per the datasheet to maintain specified conversion loss, isolation, and return loss. Leaving these pins floating will degrade HMC187AMS8 RF performance unpredictably.
What is the thermal operating range and storage limit for the HMC187AMS8?
The HMC187AMS8 is characterized for continuous operation from –40°C to +85°C ambient temperature. Its storage temperature range is –65°C to +150°C. Performance parameters-including conversion loss, isolation, and return loss-are guaranteed only within the operating range. The device uses MSL1 moisture sensitivity packaging, allowing unlimited floor life before reflow if stored properly.
Is the HMC187AMS8 compatible with lead-free reflow processes?
The HMC187AMS8E variant is RoHS-compliant with 100% matte tin lead finish and rated for peak reflow temperatures up to 260°C, making it fully compatible with standard lead-free reflow profiles. The non-E variant (HMC187AMS8) uses Sn/Pb solder and is limited to 235°C peak reflow. Both versions are MSL1-rated, but only HMC187AMS8E supports Pb-free assembly for HMC187AMS8 applications.
