Product details
Overview
HMC1058-SX from Analog Devices is a GaAs MMIC sub-harmonic mixer die operating at 71–86 GHz RF, 29–43 GHz LO, and DC–12 GHz IF, with −11 dB typical conversion loss, 43 dB 2LO/RF isolation, and no DC bias required. It serves as a passive upconverter or downconverter in E-band communications and automotive radar front-ends.
For engineers reviewing the HMC1058-SX datasheet, HMC1058-SX pinout, HMC1058-SX application, or HMC1058-SX equivalent, key selection criteria include RF/LO frequency alignment, sub-harmonic pump efficiency, 50 Ω matched ports, die-level integration requirements, and thermal management for millimeter-wave assembly.
Technical Context
The HMC1058-SX implements a passive Schottky diode-based sub-harmonic architecture, enabling LO drive at half the RF frequency (e.g., 37.25 GHz LO for 74.5 GHz RF). Its monolithic GaAs construction provides full passivation and Ti/Au metallization on all bond pads and the grounded backside.
It operates without DC bias and delivers broadband IF response from DC to 12 GHz, supporting both USB and LSB sideband operation. Performance is characterized in a 50 Ω environment using RF probing, with conversion gain and IP3 measured under defined LO power (±9 dBm) and temperature (−55°C to +85°C) conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 71–86 GHz: Supports full E-band (71–76 GHz and 81–86 GHz) licensed spectrum for high-capacity wireless links. |
| LO Frequency Range | 29–43 GHz: Enables sub-harmonic pumping-halving LO generation complexity versus fundamental mixers. |
| IF Frequency Range | DC–12 GHz: Allows baseband-to-millimeter-wave translation with wideband modulation support (e.g., OFDM, FMCW). |
| Conversion Loss | −11 dB typical: Defines signal attenuation between RF and IF paths; impacts system noise figure and dynamic range budget. |
| 2LO/RF Isolation | 43 dB: Suppresses second harmonic of LO from coupling into RF path-critical for spectral purity in sensitive receivers. |
| LO/RF Isolation | 28 dB: Limits LO leakage into antenna or RF chain, reducing self-interference and improving receiver blocking performance. |
| Die Size | 1.15 × 0.97 × 0.1 mm: Ultra-compact chip-scale form factor requiring precision wire bonding and thermal grounding via backside metal. |
Pinout & Package
Package: Unpackaged GaAs MMIC die (bare die), 0.1 mm thick, with Ti/Au metallized bond pads and grounded gold backside. Requires eutectic or conductive epoxy mounting to RF ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pad 1 | RF | 50 Ω matched input/output port for 71–86 GHz signals; must be connected via low-inductance microstrip or bond wire. |
| Pad 2 | LO | AC-coupled 50 Ω port for 29–43 GHz sub-harmonic pump; requires external DC blocking if bias injection is used elsewhere. |
| Pad 3 | IF | AC-coupled 50 Ω port for DC–12 GHz intermediate frequency; supports bidirectional use in up/downconversion. |
| Die Bottom | GND | Electrically grounded backside metallization-must be soldered or epoxied directly to RF ground plane for thermal and RF return path integrity. |
Key Features
| Feature | Design Value |
|---|---|
| No DC bias required | Eliminates bias network design, reduces component count, and avoids LO injection through bias lines in high-frequency layouts. |
| Low LO drive (9 dBm) | Reduces power consumption and heat generation in LO chains; enables use with lower-power synthesizers or frequency multipliers. |
| High 2LO/RF isolation (43 dB) | Minimizes spurious responses from LO harmonics-essential for meeting spectral mask requirements in E-band radios. |
| Wide IF bandwidth (DC–12 GHz) | Supports complex modulation schemes (e.g., 400ZR, IEEE 802.11ay) and FMCW radar chirp processing without IF filtering constraints. |
| Passivated Schottky diodes | Ensures long-term reliability under thermal cycling and humidity exposure in military and automotive environments. |
Applications
| E-Band Point-to-Point Radio | Automotive Radar Transceiver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar sub-harmonic mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048-SX | Lower RF band: 57–66 GHz; −12 dB conversion loss; 38 dB 2LO/RF isolation. | Targets V-band systems (57–66 GHz), not E-band; unsuitable for 71–86 GHz compliance-critical designs. | Select HMC1048-SX only when operating below 66 GHz and requiring marginally better conversion loss. |
| HMC1118-SX | Higher RF band: 79–90 GHz; −10.5 dB conversion loss; 40 dB 2LO/RF isolation; larger die (1.25 × 1.05 mm). | Covers upper E-band extension and W-band edge; requires revised RF layout due to different pad spacing and thermal mass. | Choose HMC1118-SX for 81–90 GHz coverage where extended upper frequency is mandatory. |
Compared with HMC1048-SX and HMC1118-SX, the HMC1058-SX uniquely balances 71–86 GHz coverage, −11 dB conversion loss, and 43 dB 2LO/RF isolation in a 1.15 × 0.97 mm footprint-making it the optimal choice for standard E-band infrastructure and radar systems requiring regulatory-compliant operation.

FAQ
What is the operating temperature range for the HMC1058-SX?
The HMC1058-SX is specified for operation from −55°C to +85°C ambient temperature. Its maximum junction temperature is 170°C, and thermal resistance (junction to die bottom) is 555°C/W-requiring direct thermal connection of the grounded backside to a heatsink or ground plane for reliable high-power operation. The HMC1058-SX performance data is validated across this full range.
Does the HMC1058-SX require DC bias voltage or current?
No, the HMC1058-SX is a passive Schottky diode-based mixer and requires no DC bias. All three ports (RF, LO, IF) are AC-coupled, with Pad 2 (LO) and Pad 3 (IF) explicitly noted as AC-coupled in the official pad description table. This eliminates bias network design complexity and potential LO injection paths. The HMC1058-SX functions solely on RF and LO signal energy.
What is the absolute maximum LO power rating for the HMC1058-SX?
The absolute maximum LO drive level for the HMC1058-SX is +20 dBm, per the Absolute Maximum Ratings table. Operation above this level risks permanent damage to the Schottky diodes. Typical characterization uses +9 dBm LO, delivering −11 dB conversion loss; exceeding +20 dBm violates safe operating area limits and voids reliability guarantees for the HMC1058-SX.
How is the HMC1058-SX mounted and grounded in practice?
The HMC1058-SX die must be mounted with its gold-plated backside directly bonded to an RF ground plane using AuSn eutectic preform (255°C work surface) or electrically conductive epoxy. Bond pads 1–3 connect via ≤12 mil gold wire bonds to 50 Ω microstrip lines on alumina substrates. The die bottom serves as the primary RF and thermal return path-floating or poorly grounded mounting degrades isolation and causes thermal runaway. This mounting method is mandatory for HMC1058-SX functionality.
Can the HMC1058-SX be used for both upconversion and downconversion?
Yes, the HMC1058-SX is bidirectional and supports both upconversion (IF → RF) and downconversion (RF → IF), as confirmed in the General Description and Typical Applications sections. Its passive architecture and symmetric 50 Ω port matching enable either mode. Measured IP3 and conversion gain data are provided separately for upconverter and downconverter configurations in the datasheet-validating dual-mode use of the HMC1058-SX.
