Product details
Overview
HMC488MS8GETR from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC double-balanced mixer with integrated LO amplifier, operating from 4–7 GHz RF/LO and DC–2.5 GHz IF. It delivers 7 dB typical conversion loss, +15 dBm input IP3, and requires only +5 V @ 46 mA for the on-chip LO buffer-enabling compact, low-power RF front-ends in wireless infrastructure transceivers.
For engineers reviewing the HMC488MS8GETR datasheet, HMC488MS8GETR pinout, HMC488MS8GETR application, or HMC488MS8GETR equivalent, this device is selected for high-linearity, wideband SMT mixing where LO drive flexibility (0 to +6 dBm), compact MSOP8-G footprint (14.8 mm²), and robust isolation (>25 dB LO-to-RF) are critical in 5G small cells, VSAT modems, and WLAN up/downconverters.
Technical Context
The HMC488MS8GETR integrates a GaAs Schottky diode quad, transformer baluns, and an on-die LO buffer amplifier in a monolithic MMIC process. Its double-balanced topology suppresses even-order harmonics and LO leakage while enabling bidirectional operation as upconverter, downconverter, or bi-phase modulator.
It operates with DC-coupled RF and IF ports (50 Ω matched), AC-coupled LO input, and dual Vdd pins supplying the LO amplifier. Thermal resistance is 75.5 °C/W (channel-to-ground paddle), supporting operation from –40 °C to +85 °C with MSL1 reflow compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 4–7 GHz - supports full-band operation in 5G FR1, UNII, and WiMAX bands without tuning |
| IF Bandwidth | DC–2.5 GHz - enables baseband I/Q and wide IF sampling in direct-conversion architectures |
| Conversion Loss | 7 dB typ. @ LO = +2 dBm - low loss preserves SNR in cascaded receiver chains |
| Input IP3 | +15 dBm @ TA = +25°C - ensures strong interferer rejection in dense RF environments |
| LO-to-RF Isolation | 25–32 dB - minimizes LO radiation into antenna paths, easing filtering requirements |
| Supply Current | 46 mA @ Vdd = +5 V - enables low-power active mixing vs. passive alternatives |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP4CE | Wider RF/LO range (3–8 GHz), higher IP3 (+18 dBm), but larger 4×4 mm QFN package | Better suited for wideband test equipment; less optimal for space-constrained small cells | Choose when wider frequency coverage and higher linearity outweigh size constraints |
| ADL5802ACPZ-R7 | Lower frequency range (700 MHz–6 GHz), integrated LO synthesizer, +5.5 V supply, no DC-coupled IF | Targets cellular infrastructure with integrated PLL; lacks DC IF capability for zero-IF designs | Prefer when system-level LO generation and lower-frequency support are required over DC IF |
Compared with HMC1048LP4CE and ADL5802ACPZ-R7, the HMC488MS8GETR uniquely balances 4–7 GHz coverage, DC-coupled IF/RF, and ultra-compact MSOP8-G packaging-making it optimal for miniaturized, high-linearity wireless infrastructure where board space and IF flexibility are critical.

FAQ
What is the operating frequency range of the HMC488MS8GETR?
The HMC488MS8GETR operates with RF and LO frequencies from 4 to 7 GHz, and IF bandwidth from DC to 2.5 GHz. This range covers key unlicensed and licensed bands including UNII-1/2/3, ISM 5.8 GHz, WiMAX 5.2–5.8 GHz, and portions of 5G FR1. The device maintains specified performance-including 7 dB typical conversion loss and >25 dB LO-to-RF isolation-across the full 4–7 GHz span at +25°C.
Does the HMC488MS8GETR require an external LO amplifier?
No, the HMC488MS8GETR integrates a GaAs LO buffer amplifier capable of accepting 0 to +6 dBm input drive, eliminating the need for an external LO driver stage. This reduces component count, PCB area, and matching complexity. The LO amplifier is powered via pins 3 and 4 (Vdd) at +5 V, drawing 46 mA typical current-enabling direct connection from low-power synthesizers or divider outputs.
Can the HMC488MS8GETR be used for zero-IF (direct-conversion) architectures?
Yes, the HMC488MS8GETR supports zero-IF operation because both its RF and IF ports are DC-coupled and 50 Ω matched. The IF port (pin 5) handles DC–2.5 GHz and tolerates ±40 mA DC current, enabling true baseband I/Q signal handling without external blocking capacitors. This makes the HMC488MS8GETR suitable for direct-conversion receivers and modulators in software-defined radio and 5G small cell platforms.
What is the recommended PCB grounding practice for the HMC488MS8GETR?
The HMC488MS8GETR requires all ground pins (2, 6, 7) and the exposed ground paddle to be soldered directly to a solid RF ground plane using multiple thermal and RF vias. Per the datasheet, insufficient grounding causes degraded isolation and increased conversion loss. Evaluation board 106829 uses Rogers 4350 substrate with optimized via placement-Aetrix recommends replicating this approach for production designs to ensure >25 dB LO-to-RF isolation and thermal stability up to +85°C.
Is the HMC488MS8GETR still in active production?
The HMC488MS8GETR is marked "OBSOLETE" in official Analog Devices documentation, indicating it is no longer in active production. However, Aetrix Electronics maintains verified legacy inventory with full traceability and extended lifecycle support-including obsolescence monitoring, cross-reference assistance, and last-time-buy coordination-for customers deploying in long-lifecycle wireless infrastructure and defense applications.
