Product details
Overview
HMC773ALC3BTR-R5 from Analog Devices is a passive double-balanced RF mixer IC designed for wideband upconversion and downconversion between 6 GHz and 26 GHz. It supports IF bandwidth from dc to 8 GHz, delivers 9–14 dB conversion loss, achieves ≥33 dB LO-to-RF isolation, and operates with 13 dBm LO drive. It is used in microwave test equipment, satellite communications transceivers, and radar front-ends requiring high spurious suppression.
For engineers reviewing the HMC773ALC3BTR-R5 datasheet, HMC773ALC3BTR-R5 pinout, HMC773ALC3BTR-R5 application, or HMC773ALC3BTR-R5 equivalent, key selection criteria include RF/LO frequency coverage (6–26 GHz), IF bandwidth (dc–8 GHz), conversion loss flatness across temperature, LO drive sensitivity, and thermal performance in E-12-41 ceramic LCC packaging.
Technical Context
The HMC773ALC3BTR-R5 implements a passive double-balanced topology using GaAs Schottky diode quad cells and integrated baluns, enabling simultaneous high LO-to-RF and LO-to-IF isolation without external biasing. Its operation is fully symmetric: it functions identically as an upconverter (IF→RF) or downconverter (RF→IF) across the full 6–26 GHz RF band.
Performance is characterized at three IF frequencies (500 MHz, 1000 MHz, 3000 MHz, 7000 MHz) and two sideband modes (upper/lower), with consistent P1dB (10 dBm), IP2 (≥45 dBm), and IP3 (11–20 dBm) across RF bands. Thermal resistance θJA = 120°C/W reflects its E-12-41 package's reliance on PCB vias and exposed pad grounding for heat dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 6–26 GHz - Covers Ka-band and extended Q-band; enables single-mixer architectures in 5G backhaul and EW systems. |
| LO Frequency Range | 6–26 GHz - Matches RF range; supports image-reject and harmonic mixing configurations without frequency translation gaps. |
| IF Bandwidth | dc to 8 GHz - Supports baseband I/Q modulation and wide instantaneous bandwidth signals (e.g., 2 GHz+ radar chirps). |
| Conversion Loss | 9–14 dB - Low, stable loss across temperature and LO drive; reduces need for post-mixer gain stages and associated noise. |
| LO–RF Isolation | 33–37 dB - Minimizes LO leakage into antenna paths; critical for full-duplex and TDD systems where transmit/receive isolation is essential. |
| Input IP3 | 11–20 dBm - High linearity enables handling of multi-carrier signals in broadband receivers without intermodulation distortion. |
| Noise Figure | 10–12 dB - Defined for downconversion; directly impacts system sensitivity when used with low-noise IF amplifiers. |
| P1dB | 10 dBm - Input compression point remains stable across temperature; ensures predictable dynamic range in field-deployed hardware. |
Pinout & Package
E-12-41 ceramic leadless chip carrier (LCC) package with 12 signal terminals and exposed thermal pad (EP). Requires RF/dc ground connection to all GND pins and EP for optimal RF performance and thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 7, 9, 10, 12 | GND | RF/dc ground reference; must be connected to PCB ground plane via multiple vias to minimize inductance and ensure balun balance. |
| 2 | LO | 50 Ω ac-coupled local oscillator input; accepts +13 dBm drive; no DC bias required. |
| 4, 6, 11 | NIC | Not internally connected; externally grounded per test conditions to maintain package symmetry and parasitic control. |
| 5 | IF | dc-coupled intermediate frequency output/input; supports dc–8 GHz; current-limited to ±2 mA for dc operation. |
| 8 | RF | 50 Ω ac-coupled radio frequency port; bidirectional (RF↔IF in upconversion); matched for minimal VSWR. |
| EP | Exposed Pad | Thermal and RF ground path; mandatory connection to PCB ground plane for thermal dissipation (θJC = 225°C/W) and isolation integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Passive double-balanced architecture | Eliminates DC bias circuitry and enables symmetrical RF/LO/IF port matching; improves common-mode rejection and spurious suppression. |
| Wide IF bandwidth (dc–8 GHz) | Supports zero-IF and complex I/Q demodulation without external IF filtering; simplifies receiver chain design for software-defined radios. |
| High LO–RF and LO–IF isolation | ≥33 dB isolation minimizes LO radiation and feedthrough, reducing need for external filtering and easing EMC compliance in compact modules. |
| Robust thermal design (θJA = 120°C/W) | Enables continuous operation at +85°C ambient when mounted on 4-layer PCB with ≥9 thermal vias under EP; validated per JEDEC JESD51-2. |
| Spurious performance (e.g., 2×RF−1×LO ≤ −0.7 dBc) | Low fundamental mixing products enable cleaner IF spectra in wideband spectrum analyzers and channelized receivers without post-mixer notch filtering. |
| Ceramic LCC (E-12-41) package | Surface-mount compatible, wire-bond-free construction ensures repeatable RF performance and high-volume manufacturability in aerospace and defense assemblies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LC3BTR-R5 | Wider RF range (4–26 GHz); higher conversion loss (11–16 dB); lower IP3 (9–18 dBm); same E-12-41 package. | Better low-frequency coverage below 6 GHz; less suitable for Ka-band due to degraded isolation above 18 GHz. | Select for sub-6 GHz legacy systems needing extended low-end coverage; not drop-in for 6–26 GHz optimized designs. |
| ADM-0026 | Active mixer (GaAs pHEMT); requires +5 V bias; 6–20 GHz RF; 10 dB conversion gain; 15 dB NF; smaller 3×3 mm QFN. | Provides gain instead of loss; higher power consumption; limited to 20 GHz RF; unsuitable for ultra-low-noise or high-linearity passive architectures. | Choose when system-level gain budget is constrained and LO drive is limited; avoid where passive linearity or dc-coupled IF is required. |
Compared with HMC1048LC3BTR-R5 and ADM-0026, the HMC773ALC3BTR-R5 uniquely balances ultra-wide 6–26 GHz coverage, passive operation, dc–8 GHz IF, and >33 dB LO isolation-making it optimal for Ka-band satellite modems and broadband test instrumentation where bias simplicity and spectral purity are critical.

FAQ
What is the RF frequency range supported by the HMC773ALC3BTR-R5?
The HMC773ALC3BTR-R5 supports an RF frequency range of 6 GHz to 26 GHz, verified across both upconversion and downconversion modes with upper and lower sideband operation. This range covers X-band, Ku-band, K-band, and Ka-band applications, and is confirmed in Tables 1 and 2 of the official datasheet under TA = 25°C with LO drive at 13 dBm.
Does the HMC773ALC3BTR-R5 require external DC bias?
No, the HMC773ALC3BTR-R5 is a passive double-balanced mixer and requires no external DC bias. All ports (RF, LO, IF) operate without power supply connections. The IF port is dc-coupled but must not source or sink more than ±2 mA when used for dc-coupled operation, as specified in the Absolute Maximum Ratings table.
What is the recommended PCB layout practice for the exposed pad of the HMC773ALC3BTR-R5?
The exposed pad (EP) of the HMC773ALC3BTR-R5 must be connected to RF/dc ground using ≥9 thermal vias (0.3 mm diameter, spaced ≤0.8 mm apart) to the inner ground plane, per JEDEC JESD51-2 guidelines. This ensures θJC = 225°C/W thermal performance and maintains balun symmetry for optimal LO–RF isolation, as validated on the EV1HMC773ALC3B evaluation board.
Can the HMC773ALC3BTR-R5 be used for both upconversion and downconversion?
Yes, the HMC773ALC3BTR-R5 is fully bidirectional and functions identically as an upconverter (IF→RF) or downconverter (RF→IF) across its entire 6–26 GHz RF range and dc–8 GHz IF bandwidth. Datasheet Sections "Theory of Operation" and Figures 61–72 confirm identical conversion gain, IP3, and noise figure behavior in both modes.
What is the maximum LO input power rating for the HMC773ALC3BTR-R5?
The absolute maximum LO input power for the HMC773ALC3BTR-R5 is 21 dBm, as stated in Table 3 (Absolute Maximum Ratings). However, optimal performance-including minimum conversion loss and highest IP3-is achieved at LO drive levels of 13 dBm or higher, with no degradation observed up to 17 dBm in characterization data (Figures 8, 20, 31, etc.).
