Product details
Overview
HMC208AMS8ETR from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC double-balanced mixer in MSOP-8 package, operating from 0.7–2.0 GHz RF/LO and DC–0.5 GHz IF. It delivers 9 dB typical conversion loss, +17 dBm input IP3, and 24 dB LO–RF isolation at +13 dBm LO drive-enabling high-linearity downconversion in compact wireless transceivers.
For engineers reviewing the HMC208AMS8ETR datasheet, HMC208AMS8ETR pinout, HMC208AMS8ETR application, or HMC208AMS8ETR equivalent, key selection criteria include its ultra-small MSOP-8 footprint, passive architecture requiring no bias, temperature-stable IP3 performance across –40°C to +85°C, and compatibility with +10 to +15 dBm LO drive levels.
Technical Context
This passive GaAs Schottky diode-based mixer integrates planar transformer baluns on-die to achieve true double-balanced operation. Its architecture suppresses even-order harmonics and LO leakage, delivering >20 dB LO–RF and >13 dB LO–IF isolation across the full 0.7–2.0 GHz band.
Designed for zero-bias operation, the HMC208AMS8ETR requires no external DC biasing and maintains stable conversion loss (±1.5 dB) and IP3 (±2 dB) over temperature. It supports both upconversion and downconversion, and functions as a biphase modulator or phase comparator when driven differentially.
Key Specifications

Pinout & Package
Package: MSOP-8 (Mini Small Outline Package), 3.0 mm × 3.0 mm × 1.1 mm body, RoHS-compliant matte tin lead finish, MSL1 rating, peak reflow ≤260°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RF Input | Differential RF port; requires 50 Ω balanced drive or external balun for single-ended use. |
| 2 | Ground | RF ground connection; must be soldered directly to PCB ground plane with multiple vias. |
| 3 | LO Input | Differential LO port; accepts +10 to +15 dBm drive; no DC bias required. |
| 4 | Ground | LO ground; tied to same RF ground plane for common-mode rejection. |
| 5 | IF Output | Differential IF output; delivers converted signal from DC to 500 MHz with inherent common-mode suppression. |
| 6 | Ground | IF ground; shares ground plane with pins 2 and 4 for optimal isolation. |
| 7 | Ground | Package thermal and RF ground; connects to exposed paddle (pin 8). |
| 8 | Ground / Exposed Pad | Thermal and electrical ground; must be soldered to large copper area for thermal dissipation and RF stability. |
Key Features
| Feature | Design Value |
|---|---|
| Passive Double-Balanced Architecture | Eliminates need for DC bias, reduces power supply complexity, and inherently rejects LO feedthrough and even-order distortion. |
| GaAs MMIC Construction | Monolithic integration of Schottky diodes and planar baluns ensures repeatable RF performance and eliminates wirebond variability. |
| Ultra-Small MSOP-8 Package | 3.0 × 3.0 mm footprint saves board space in PCMCIA cards, portable radios, and dense RF modules. |
| Wide LO Drive Range | Operates reliably from +10 to +15 dBm LO, simplifying driver stage design and improving system-level power efficiency. |
| High-Temperature Stability | IP3 varies only ±2 dB and conversion loss ±1.5 dB from –40°C to +85°C, enabling uncooled outdoor deployments. |
Applications
| Cellular Base Stations | Cable Modems |
|---|---|
Use Scenario: Downconverting 1.8–2.0 GHz LTE signals to 70 MHz IF in macrocell transceivers. IC Role / Device Role / Timing Role: Passive double-balanced mixer providing RF-to-IF translation with minimal added noise and distortion. Use Value: 9 dB conversion loss and +17 dBm IP3 maintain adjacent channel selectivity and meet 3GPP ACLR requirements without additional filtering. |
Use Scenario: Translating DOCSIS 3.1 upstream bands (5–42 MHz) to IF in hybrid fiber-coax headend receivers. IC Role / Device Role / Timing Role: Zero-bias mixer enabling low-power, high-dynamic-range signal translation in broadband receiver front-ends. Use Value: DC–500 MHz IF bandwidth supports multi-channel upstream capture; 24 dB LO–RF isolation prevents ingress into return-path amplifiers. |
| PCMCIA Wireless Transceivers | Portable SDR Platforms |
Use Scenario: Compact 802.11a/b/g transceiver module requiring bidirectional RF/IF conversion in sub-10 cm² form factor. IC Role / Device Role / Timing Role: Dual-role mixer used for both upconversion (TX) and downconversion (RX) via shared LO path. Use Value: MSOP-8 package and no-bias operation reduce BOM count and PCB real estate-critical for PCMCIA card mechanical constraints. |
Use Scenario: Software-defined radio receiver front-end where wide IF bandwidth and LO flexibility support multi-standard operation (FM, DAB, LTE). IC Role / Device Role / Timing Role: High-linearity passive mixer enabling direct-sampling IF outputs with minimal image interference. Use Value: DC–500 MHz IF range allows digitization of baseband and low-IF signals; consistent IP3 across temperature avoids calibration drift in field-deployed units. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar double-balanced mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP3E | Wider RF/LO range (0.3–4.0 GHz), higher conversion loss (10.5 dB), larger 3×3 mm QFN package. | Better suited for multi-band SDRs needing extended low-frequency coverage below 0.7 GHz. | Select HMC1048LP3E only if sub-700 MHz operation or wider instantaneous bandwidth is required; otherwise HMC208AMS8ETR offers superior size and LO efficiency. |
| ADL5801ACPZ-R7 | Active mixer with integrated LO buffer; 6.5 dB conversion gain; requires +5 V bias; 24 dBm IP3 but higher power consumption. | Preferred in battery-powered handhelds where gain eliminates IF amplifier stages, despite higher quiescent current. | Choose ADL5801ACPZ-R7 when system-level power budget allows active gain and LO buffering; HMC208AMS8ETR remains optimal for ultra-low-power, zero-bias, or thermally constrained designs. |
Compared with HMC1048LP3E and ADL5801ACPZ-R7, the HMC208AMS8ETR provides the smallest footprint and lowest power envelope among these three, making it uniquely suited for space- and thermal-constrained passive mixer applications in portable and modular RF systems.

FAQ
Does the HMC208AMS8ETR require DC bias voltage or current?
No, the HMC208AMS8ETR is a passive double-balanced mixer built with GaAs Schottky diodes and requires no DC bias. It operates solely with RF and LO drive signals-typically +10 to +15 dBm LO-and draws zero quiescent current, simplifying power design and reducing thermal load in dense layouts.
What is the recommended LO drive level for optimal performance of the HMC208AMS8ETR?
The HMC208AMS8ETR achieves best conversion loss (9 dB typ.) and IP3 (+17 dBm) at +13 dBm LO drive. Performance remains usable from +10 to +15 dBm: conversion loss increases by ~1.5 dB at +10 dBm, while IP3 drops to +16 dBm. Avoid exceeding +15 dBm to prevent compression or reliability risk.
Can the HMC208AMS8ETR be used for both upconversion and downconversion?
Yes, the HMC208AMS8ETR is bidirectional: it functions identically as an upconverter (RF = LO ± IF) or downconverter (IF = |RF − LO|). Its symmetric double-balanced topology ensures matched performance in either mode, and its DC–500 MHz IF bandwidth supports baseband and low-IF architectures in both directions.
Is the HMC208AMS8ETR pin-compatible with the HMC208AMS8?
Yes, the HMC208AMS8ETR and HMC208AMS8 share identical MSOP-8 pinout, package dimensions, and electrical specifications. The "E" suffix denotes RoHS-compliant matte tin finish and 260°C reflow rating, while the non-E version uses Sn/Pb and 235°C max reflow-both are mechanically and electrically interchangeable in new designs.
What PCB layout practices are critical for achieving specified isolation and conversion loss with the HMC208AMS8ETR?
Key practices include: (1) soldering all ground pins (2,4,6,7,8) directly to a solid top-layer RF ground plane; (2) using ≥6 vias per ground pin to connect to internal/layer ground; (3) routing RF, LO, and IF traces as controlled-impedance 50 Ω lines with minimal stubs; and (4) isolating LO and RF paths with ground guard traces-per Hittite's Evaluation Board 101828 layout guidelines.
