Product details
Overview
HMC1106 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC double-balanced passive mixer designed for microwave downconversion in RF front-ends. It operates with 15–36 GHz RF input, 20–50 GHz LO drive, and delivers DC–24 GHz IF output, requiring no DC bias and only +15 dBm LO power. It is used in high-frequency point-to-point radios and automotive radar systems.
For engineers reviewing the HMC1106 datasheet, HMC1106 pinout, HMC1106 application, or HMC1106 equivalent, key selection criteria include its wide IF bandwidth, low conversion loss (typ. 11 dB), high LO/RF isolation (38 dB), and die-level integration for millimeter-wave system-on-substrate designs.
Technical Context
The HMC1106 implements a passive double-balanced diode ring architecture using fully passivated GaAs Schottky diodes, enabling broadband operation without DC bias. Its symmetrical topology provides inherent suppression of even-order harmonics and local oscillator leakage.
All three ports-LO, RF, and IF-are impedance-matched to 50 Ω via on-die AC coupling (LO, RF) or DC coupling (IF), with the die backside metallized as RF/DC ground. Thermal resistance is 570 °C/W, supporting continuous operation up to +85 °C ambient with junction temperature limited to 175 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048 | Lower RF band (10–26 GHz), higher conversion loss (13 dB typ.), same die size and LO drive | Better suited for X-band radar than Ka-band systems | Select when operating below 26 GHz and board space is constrained |
| QPC1006 | Higher LO power requirement (+19 dBm), wider IF bandwidth (DC–40 GHz), GaN-based | Targeted at high-dynamic-range EW receivers, not commercial SATCOM | Choose only if >24 GHz IF output or >+17 dBm LO headroom is mandatory |
Compared with HMC1048 and QPC1006, the HMC1106 uniquely balances Ka-band RF coverage (15–36 GHz), moderate LO drive (+15 dBm), and DC–24 GHz IF output in a 1.79 × 1.46 mm die-making it optimal for cost-sensitive, high-volume millimeter-wave radios where layout simplicity and thermal manageability are critical.

FAQ
What is the recommended LO drive level for optimal performance of the HMC1106?
The HMC1106 achieves best conversion loss and IP3 performance at +15 dBm LO power, as validated in all electrical specifications tables. Operation between +13 dBm and +17 dBm is supported, but deviation beyond this range increases conversion loss by up to 3 dB and degrades isolation by 4–6 dB per 2 dB LO change. The HMC1106 datasheet specifies +15 dBm as the reference condition for all RF/IF/LO isolation and conversion loss metrics.
Does the HMC1106 require DC biasing or external matching components?
No, the HMC1106 is a fully passive double-balanced mixer with no DC bias pins or requirements. All ports-LO (Pad 1), RF (Pad 2), and IF (Pad 3)-are internally matched to 50 Ω: LO and RF via integrated AC coupling, IF via DC coupling. No external baluns, bias tees, or matching networks are needed for standard operation in a 50 Ω environment, simplifying PCB layout and reducing insertion loss.
What is the maximum operating temperature and thermal derating for the HMC1106?
The HMC1106 has an operating temperature range of –55 °C to +85 °C ambient, with absolute maximum junction temperature of 175 °C. At +85 °C ambient, its continuous power dissipation is rated at 157 mW, derating linearly at 1.75 mW/°C above that. Its thermal resistance (junction-to-die-bottom) is 570 °C/W, so effective heat sinking via eutectic or conductive epoxy bonding to a grounded metal carrier is essential for sustained high-power operation.
Can the HMC1106 be used for upconversion applications?
The HMC1106 is characterized and optimized for downconversion (RF → IF with LO injection), and its datasheet provides no guaranteed performance data for upconversion mode. While the double-balanced topology is theoretically bidirectional, RF-to-IF isolation (25 dB typ.) and IF port DC coupling make it unsuitable for transmitting applications where IF port must handle high-power RF output. Use only as specified: downconverter with RF input, LO input, and IF output.
What packaging options are available for the HMC1106?
The HMC1106 is supplied exclusively as a bare die (unpacked GaAs MMIC chip) in Gel Pack (GP-2) format. No leaded, QFN, or module variants exist. Die dimensions are 1.79 × 1.46 × 0.1 mm, with Ti/Au bond pads and gold backside metallization. Alternate packaging requires custom assembly; contact Analog Devices for die-on-carrier or flip-chip evaluation options.
