Product details
Overview
HMC8191LC4TR from Analog Devices is a passive, wideband I/Q monolithic microwave integrated circuit (MMIC) mixer operating from 6 GHz to 26.5 GHz RF/LO with dc–5 GHz IF bandwidth. It delivers 9 dB typical conversion loss, 25 dBc image rejection, and ±5° phase balance in downconverter mode, enabling high-fidelity signal translation in microwave receiver and transmitter architectures.
For engineers reviewing the HMC8191LC4TR datasheet, HMC8191LC4TR pinout, HMC8191LC4TR application, or HMC8191LC4TR equivalent, this page provides verified RF performance data, validated terminal functions, thermal design guidance for GaAs MMIC operation, and real-world use cases in test instrumentation and defense-grade microwave links.
Technical Context
The HMC8191LC4TR integrates a 90-degree hybrid and passive mixer cells on a GaAs MESFET process, supporting both image-reject downconversion and single-sideband upconversion without DC bias. Its I/Q architecture inherently suppresses image sidebands, eliminating external filtering requirements for precision microwave systems.
It operates with single-ended RF, LO, and IF ports, all dc-coupled and 50 Ω matched when LO is active. The device requires no power supply, exhibits low noise figure (9 dB SSB NF), and maintains amplitude/phase balance across temperature (−40°C to +85°C) and LO drive (14–20 dBm).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 6 GHz to 26.5 GHz - supports full K-band and Ka-band operation in radar, SATCOM, and 5G backhaul. |
| IF Bandwidth | DC to 5 GHz - enables baseband-to-microwave direct sampling and complex modulation schemes. |
| Conversion Loss | 9 dB typical - defines signal attenuation through passive mixing; impacts system noise figure and gain budget. |
| Image Rejection | 25 dBc typical - quantifies suppression of unwanted image sideband without external filters. |
| Input IP3 | 24 dBm typical (downconverter) - determines third-order intermodulation distortion floor in multi-tone RF environments. |
| Phase Balance | ±5° typical - critical for quadrature accuracy in coherent demodulation and vector signal analysis. |
| LO–RF Isolation | 40 dB typical - limits LO leakage into antenna paths, preserving transmit/receive isolation in T/R modules. |
Pinout & Package
Exposed pad, 4 mm × 4 mm, 24-terminal ceramic leadless chip carrier (LCC) package with RF/dc ground-connected base. Thermal resistance θJA = 38.3°C/W (PCB with 4×4 vias).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–6, 13–15, 17–22 | GND | RF/dc ground terminals - must be soldered to solid ground plane; critical for impedance matching and thermal dissipation. |
| 7–9, 11, 24 | NC | No-connect pins - may be grounded without affecting RF performance or thermal behavior. |
| 10, 12 | IF1, IF2 | Quadrature IF input/output - dc-coupled; limited to ±3 mA current; requires external blocking caps if dc-blocking needed. |
| 16 | RF | Radio frequency port - 50 Ω matched when LO is active; dc-coupled; handles up to 24 dBm RF input. |
| 23 | LO | Local oscillator port - 50 Ω matched when active; dc-coupled; requires 18 dBm nominal drive for specified performance. |
| EPAD | Exposed Pad | Thermal and electrical ground - must be soldered to PCB ground plane with thermal vias for reliability and θJA compliance. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar I/Q mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LC4TR | Lower RF range (4–18 GHz); 3.5 GHz max IF bandwidth; 10 dB conversion loss. | Better suited for C/X-band radar and satellite modems below 18 GHz. | Select for cost-sensitive C/X-band designs where 26.5 GHz coverage is unnecessary. |
| ADMV1013ACPZ | Active I/Q mixer with integrated LO synthesizer; 24–44 GHz RF; requires 5 V DC supply. | Enables fully integrated microwave transceivers but adds power and thermal overhead. | Choose when LO integration and extended upper band coverage outweigh passive simplicity. |
Compared with HMC1048LC4TR and ADMV1013ACPZ, the HMC8191LC4TR uniquely balances ultra-wide 6–26.5 GHz coverage, true dc-coupled IF, and zero-power operation-making it optimal for high-reliability, thermally constrained, or filterless microwave receiver designs.

FAQ
What is the operating temperature range for the HMC8191LC4TR?
The HMC8191LC4TR operates over −40°C to +85°C ambient temperature. Performance specifications-including conversion loss, image rejection, and phase balance-are characterized across this full range, and thermal design must follow JESD51-2 guidelines with 4×4 thermal vias under the exposed pad to maintain θJA ≤ 38.3°C/W.
Does the HMC8191LC4TR require a DC power supply?
No, the HMC8191LC4TR is a passive mixer and requires no DC power supply. It operates solely on RF and LO signal energy. This eliminates power regulation, heat generation, and associated noise sources-making it ideal for low-SWaP (Size, Weight, and Power) microwave systems where the HMC8191LC4TR is deployed.
Can the HMC8191LC4TR be used for both upconversion and downconversion?
Yes, the HMC8191LC4TR supports both modes: as an image-reject downconverter (receiving) and a single-sideband upconverter (transmitting). Its I/Q architecture enables sideband-selective operation in either direction, with documented performance for IF = 100 MHz, 2500 MHz, and 5000 MHz in both lower- and upper-sideband configurations.
What is the maximum RF input power rating for the HMC8191LC4TR?
The absolute maximum RF input power for the HMC8191LC4TR is 24 dBm, per the Absolute Maximum Ratings table. Operating continuously near this limit requires careful thermal management via the exposed pad and PCB ground plane; derating is recommended for reliability in high-duty-cycle pulsed applications involving the HMC8191LC4TR.
How is the exposed pad of the HMC8191LC4TR connected in layout?
The exposed pad (EPAD) of the HMC8191LC4TR must be soldered directly to the PCB's RF/dc ground plane using a minimum of 4×4 array of thermal vias (0.3 mm diameter, 0.8 mm pitch) filled with solder. This connection is mandatory-not optional-for achieving specified thermal resistance (θJA = 38.3°C/W) and maintaining RF return loss ≥15 dB across the full 6–26.5 GHz band.
