Product details
Overview
HMC-MDB171 from Analog Devices is a GaAs HBT-based monolithic I/Q mixer die operating at 35–45 GHz RF/LO and DC–5 GHz IF, delivering 25 dB image rejection, 35 dB LO-to-RF isolation, and 11 dB typical conversion loss with external quadrature hybrid-used in millimeter-wave point-to-point radios and SATCOM downconverters.
For engineers reviewing the HMC-MDB171 datasheet, HMC-MDB171 pinout, HMC-MDB171 application, or HMC-MDB171 equivalent, key selection criteria include its passive operation (no DC bias), Ti/Au metallized bond pads, 1.5 × 2.0 mm die size, and compatibility with thermosonic wire bonding and eutectic die attach in MCM/hybrid microcircuit assemblies.
Technical Context
The HMC-MDB171 implements a passive double-balanced I/Q architecture using GaAs Heterojunction Bipolar Transistor (HBT) Schottky diode technology, enabling image-reject downconversion without DC power. It requires an external 90° hybrid on the IF ports to achieve 25 dB image rejection and operates with +16 dBm LO drive.
Its RF, LO, and IF ports are all DC-coupled and impedance-matched to 50 Ω, supporting both IRM and single-sideband upconversion modes. The die backside is fully metallized with Ti/Au and serves as RF ground, enabling direct eutectic or conductive-epoxy mounting to a grounded substrate.

Equivalent & Alternatives
The following parts are listed as comparable options for similar I/Q mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC-MDB170 | Same die family, but rated for 24–34 GHz RF/LO range; 22 dB image rejection | Lower-frequency E-band alternatives; not suitable for 35–45 GHz systems | Select only when operating below 34 GHz and lower image rejection is acceptable |
| HMC1040LP4E | 40–60 GHz active I/Q mixer with integrated LO buffer; requires +5 V bias; 20 dB image rejection | Higher-frequency coverage but adds power, noise, and layout complexity | Choose when wider RF band (up to 60 GHz) and active gain are needed despite higher power and cost |
Compared with HMC-MDB170 and HMC1040LP4E, the HMC-MDB171 uniquely balances 35–45 GHz operation, passive simplicity, and 25 dB image rejection in a 1.5 × 2.0 mm die-making it optimal for size-constrained, bias-free E-band downconverters where thermal stability and LO leakage control are critical.

FAQ
What is the recommended LO drive level for optimal performance of the HMC-MDB171?
The HMC-MDB171 is characterized at +16 dBm LO input power, which delivers specified conversion loss (11 dB typ), image rejection (25 dB typ), and IP3 (17 dBm). Operating below +14 dBm increases conversion loss and degrades linearity; exceeding +17 dBm risks compression and reliability concerns. Always maintain LO within ±0.5 dB tolerance for repeatable RF performance in production assemblies.
Does the HMC-MDB171 require DC bias or external power to operate?
No, the HMC-MDB171 is a fully passive GaAs MMIC I/Q mixer and requires no DC bias or external power supply. Its operation relies solely on RF and LO signal energy, eliminating bias networks, decoupling capacitors, and associated noise sources-making it ideal for ultra-low-power and thermally sensitive millimeter-wave modules.
How is image rejection achieved with the HMC-MDB171, and what external components are needed?
Image rejection in the HMC-MDB171 is achieved using an external 90° hybrid coupler connected to the IF1 and IF2 ports. The hybrid combines the I and Q outputs to cancel the image sideband. Without the hybrid, the device functions as a standard double-balanced mixer with no inherent image rejection-so the hybrid is mandatory for IRM mode and contributes +3 dB to measured conversion loss.
What are the handling and mounting requirements for the HMC-MDB171 die?
The HMC-MDB171 is an electrostatic-sensitive GaAs die requiring ESD-safe handling per MIL-STD-883 Method 2010. Mounting must use AuSn eutectic (255 °C work surface) or conductive epoxy; backside Ti/Au metallization serves as ground. Bond wires should be ≤0.31 mm long, and substrates must minimize die-to-line spacing to preserve 35–45 GHz impedance integrity.
Can the HMC-MDB171 be used for upconversion, and what configuration is required?
Yes, the HMC-MDB171 supports single-sideband upconversion by applying baseband I/Q signals to IF1 and IF2 while injecting the LO at port 3 and extracting the RF output at port 1. This configuration leverages the same passive I/Q architecture-no reconfiguration or external switching is needed, and performance matches downconversion specs when IF signals are properly balanced and phase-aligned.
