Product details
Overview
HMC8191LC4TR-R5 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 and dc–5 GHz IF. It delivers 9 dB typical conversion loss, 25 dBc image rejection, and 24 dBm input IP3 in downconverter mode, enabling high-dynamic-range signal translation in microwave receivers and transmitters.
For engineers reviewing the HMC8191LC4TR-R5 datasheet, HMC8191LC4TR-R5 pinout, HMC8191LC4TR-R5 application, or HMC8191LC4TR-R5 equivalent, this page provides verified RF performance data, validated 24-pin LCC package mapping, confirmed I/Q architecture behavior, and real-world design constraints for test instrumentation and defense-grade microwave systems.
Technical Context
The HMC8191LC4TR-R5 implements a GaAs MESFET-based passive I/Q mixer core with integrated 90° hybrid at IF ports, supporting both image-reject downconversion and single-sideband upconversion. Its inherent quadrature architecture enables simultaneous amplitude- and phase-balanced IF1/IF2 paths without external hybrids in many configurations.
It operates without DC bias-requiring only LO drive (18 dBm typical)-and achieves 15 dBm P1dB compression while maintaining 15 dB RF/LO/IF return loss across its full band. Thermal design centers on the exposed pad (EPAD), which must be RF/dc grounded per JEDEC JESD51-2 guidelines for θJC = 137°C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 6 GHz to 26.5 GHz - supports Ka-band radar, satellite comms, and 5G FR2 test equipment without band switching. |
| IF Bandwidth | dc to 5 GHz - enables baseband I/Q sampling and wide instantaneous bandwidth capture in vector signal analyzers. |
| Conversion Loss | 9 dB typical - defines minimum gain budget required in cascaded receiver chains; no DC power needed. |
| Image Rejection | 25 dBc typical - reduces need for post-mixer image filtering, lowering system BOM cost and insertion loss. |
| Input IP3 | 24 dBm (downconverter) - determines third-order intermodulation headroom in multi-tone RF environments like EW systems. |
| LO–RF Isolation | 40 dB typical - minimizes LO leakage into antenna paths, critical for full-duplex and TDD architectures. |
| Amplitude Balance | ±0.5 dB - ensures matched I/Q path gain for <0.1 dB EVM degradation in high-order QAM modems. |
| Phase Balance | ±5° - preserves quadrature orthogonality for >35 dB sideband suppression in SSB upconverters. |
Pinout & Package
Package: Exposed-pad, 4 mm × 4 mm, 24-terminal ceramic leadless chip carrier (LCC), RoHS-compliant, operating temperature −40°C to +85°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–6, 13–15, 17–22 | GND | RF/dc ground terminals - must be soldered to solid ground plane with thermal vias; EPAD grounding is mandatory. |
| 7–9, 11, 24 | NC | No-connect pins - may be grounded without affecting RF performance or thermal dissipation. |
| 10, 12 | IF1, IF2 | Quadrature IF ports - dc-coupled; current-limited to ±3 mA; require external dc blocking caps if dc not needed. |
| 16 | RF | Radio frequency port - 50 Ω matched when LO active; handles up to 24 dBm RF input (absolute max). |
| 23 | LO | Local oscillator port - 50 Ω matched when active; requires 18 dBm drive for specified conversion loss and linearity. |
| EPAD | Exposed Pad | Thermal and RF ground - must be soldered to PCB ground plane; primary thermal path (θJC = 137°C/W). |
Key Features
| Feature | Design Value |
|---|---|
| Passive I/Q architecture | Eliminates DC biasing complexity and associated noise; enables ultra-low-noise figure (9 dB SSB NF) vs. active mixers. |
| Wideband 6–26.5 GHz operation | Replaces multiple narrowband mixers in multi-band test sets, reducing calibration overhead and board area. |
| Integrated 90° hybrid interface | Supports direct connection of I/Q baseband ICs without external hybrids-reducing insertion loss and layout sensitivity. |
| High LO-to-RF/IF isolation (40 dB) | Prevents LO radiation from corrupting sensitive receive paths or violating EMC limits in compact enclosures. |
| DC-coupled IF ports | Enables true baseband I/Q generation and demodulation for zero-IF architectures used in software-defined radios. |

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 (4–16 GHz); 10 dB conversion loss; 22 dBc image rejection; same 24-pin LCC package. | Better suited for C/X-band radar; insufficient for Ka-band 26.5 GHz upper limit. | Select when operating below 16 GHz and lower cost is prioritized over bandwidth. |
| Qorvo QM11020 | Active I/Q mixer; requires ±5 V bias; 6–20 GHz RF; 11 dB conversion gain; 20 dBc image rejection. | Provides gain but adds noise (12 dB NF); unsuitable for ultra-low-noise receiver front-ends. | Choose only when system-level gain budget is negative and LO drive is constrained. |
Compared with HMC1048LC4TR and QM11020, the HMC8191LC4TR-R5 uniquely delivers Ka-band coverage up to 26.5 GHz with passive low-noise operation and superior image rejection-making it irreplaceable in wideband test equipment and high-frequency defense electronics where spectral purity and bandwidth are non-negotiable.

FAQ
What is the recommended LO drive level for optimal performance of the HMC8191LC4TR-R5?
The HMC8191LC4TR-R5 is characterized at 18 dBm LO drive, delivering 9 dB typical conversion loss, 25 dBc image rejection, and 24 dBm input IP3. Deviating below 16 dBm increases conversion loss and degrades linearity; exceeding 20 dBm risks reliability due to absolute maximum rating limits. Always maintain LO match to 50 Ω.
Can the HMC8191LC4TR-R5 operate with dc-coupled IF signals?
Yes-the HMC8191LC4TR-R5 IF1 and IF2 ports are dc-coupled and support true baseband operation. However, each IF pin must not source or sink more than ±3 mA; exceeding this violates absolute maximum ratings and may cause functional failure. External dc blocking capacitors are required if dc coupling is unnecessary.
Does the HMC8191LC4TR-R5 require external 90° hybrids for I/Q operation?
No-the HMC8191LC4TR-R5 integrates internal 90° hybrid functionality at the IF ports. External hybrids are optional and used only to extend IF bandwidth beyond 5 GHz or improve amplitude/phase balance in demanding applications. Standard operation uses direct I/Q baseband connections.
What is the thermal management requirement for continuous operation of the HMC8191LC4TR-R5?
The HMC8191LC4TR-R5 requires the exposed pad (EPAD) to be soldered to a thermally robust ground plane with ≥4×4 array of 0.3 mm vias to inner ground layers. At TA = 85°C, derating is 7.29 mW/°C above ambient; maximum junction temperature is 175°C. PCB layout must follow JESD51-2 thermal impedance guidelines.
Is the HMC8191LC4TR-R5 suitable for upconversion applications?
Yes-the HMC8191LC4TR-R5 supports single-sideband upconversion with 25 dBc sideband rejection and 9 dB typical conversion loss. It operates with either high-side or low-side LO injection and maintains 22 dBm input IP3 in upconverter mode, making it suitable for clean SSB signal generation in microwave transmitters.
