Product details
Overview
HMC-MDB277 from Analog Devices is a GaAs MMIC passive double-balanced mixer die operating at 70–90 GHz RF/LO and DC–18 GHz IF, with 12 dB typical conversion loss, +14 dBm LO drive requirement, and 1.55 × 1.4 × 0.1 mm die size-designed for millimeter-wave up/downconversion in E-band radios and automotive radar front-ends.
For engineers reviewing the HMC-MDB277 datasheet, HMC-MDB277 pinout, HMC-MDB277 application, or HMC-MDB277 equivalent, key selection criteria include its fundamental mixing architecture, DC-coupled 50 Ω matched ports (IF/RF/LO), wide IF bandwidth supporting baseband-to-18 GHz signals, and compatibility with thermosonic wire bonding and eutectic die attach in MCM/hybrid assemblies.
Technical Context
The HMC-MDB277 implements a passive double-balanced topology using GaAs HBT Schottky diode technology, enabling broadband operation without DC bias. Its three-port configuration (RF, LO, IF) supports both upconversion and downconversion with no internal active circuitry or matching components required.
All bond pads and the backside are Ti/Au metallized and fully passivated; the grounded backside serves as RF return path, and each port is DC-coupled and impedance-matched to 50 Ω-enabling direct integration into microstrip-based millimeter-wave circuits on alumina substrates.
Key Specifications

| RF/LO Frequency Range | 70–90 GHz: Enables operation across full E-band (71–76 GHz & 81–86 GHz) for FCC-compliant wireless links. |
| IF Bandwidth | DC–18 GHz: Supports baseband I/Q signals and wideband modulation schemes up to 18 GHz IF output. |
| Conversion Loss | 12 dB typical: Defines signal attenuation between RF and IF paths under +14 dBm LO drive-critical for link budget planning. |
| LO Drive Level | +14 dBm: Required LO power level for optimal linearity and conversion efficiency; exceeds minimum but below +20 dBm absolute max. |
| Die Size | 1.55 × 1.4 × 0.1 mm: Ultra-compact footprint suitable for high-density MCMs and space-constrained millimeter-wave modules. |
| Operating Temp | −55 °C to +85 °C: Specifies usable ambient range for deployment in automotive and outdoor infrastructure environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar millimeter-wave mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC-MDB276 | Same die family; operates at 60–80 GHz RF/LO range with identical 12 dB conversion loss and +14 dBm LO drive. | Targeted at V-band systems (60 GHz unlicensed/WiGig), not E-band; lower upper-frequency limit restricts use in 81–86 GHz links. | Select HMC-MDB276 only when system RF band falls entirely within 60–80 GHz and E-band compliance is not required. |
| HMC-MDB278 | Extended RF/LO range of 80–100 GHz; otherwise identical topology, conversion loss, and packaging. | Suitable for W-band applications (94 GHz imaging/sensing); over-spec'd for E-band, with higher LO phase noise sensitivity above 90 GHz. | Choose HMC-MDB278 if future-proofing for >90 GHz extensions is needed-but verify LO source stability beyond 90 GHz. |
Compared with HMC-MDB276 and HMC-MDB278, the HMC-MDB277 offers optimal trade-off between E-band coverage (70–90 GHz), proven conversion loss, and thermal robustness-making it the preferred choice for production FCC E-band radios and 77 GHz radar where exact band alignment matters.

FAQ
What is the recommended LO drive level for optimal performance of the HMC-MDB277?
The HMC-MDB277 requires +14 dBm LO drive for specified 12 dB typical conversion loss and linearity. Operating below this level increases conversion loss; exceeding +20 dBm risks permanent damage per absolute maximum ratings. The HMC-MDB277 must be driven within this window to maintain performance across its 70–90 GHz RF/LO band.
Is the HMC-MDB277 suitable for DC-coupled IF interfaces?
Yes-the HMC-MDB277 IF port is DC-coupled and 50 Ω matched, enabling direct connection to baseband amplifiers or high-speed ADCs without blocking capacitors. This preserves low-frequency response critical for FMCW radar and zero-IF architectures. The HMC-MDB277's DC-coupled design eliminates low-frequency roll-off seen in AC-coupled alternatives.
What substrate thickness is recommended for RF interconnects to the HMC-MDB277?
A 0.127 mm (5 mil) thick alumina thin-film substrate is recommended for microstrip routing to the HMC-MDB277. If 0.254 mm (10 mil) substrates are used, the HMC-MDB277 die must be raised 0.150 mm (6 mils) via molybdenum heat spreader to maintain coplanarity-ensuring consistent impedance and minimal radiation loss at 70–90 GHz.
Does the HMC-MDB277 require DC bias voltage or current?
No-the HMC-MDB277 is a fully passive double-balanced mixer with no active transistors or bias circuitry. It operates solely on RF, LO, and IF signal energy. No external DC bias is needed, simplifying power design and eliminating bias-related drift or noise sources in sensitive millimeter-wave receivers.
How is thermal management handled for the HMC-MDB277 in high-power applications?
The HMC-MDB277 die features a grounded Ti/Au backside metallization compatible with AuSn eutectic die attach to copper or molybdenum heat spreaders. For sustained operation near +85 °C ambient, Analog Devices recommends attaching the HMC-MDB277 to a 0.150 mm moly-tab to enhance thermal conduction-verified in hybrid MCM implementations per handling notes.
