Product details
Overview
HMC292LC3BTR from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC passive double-balanced mixer designed for RF/LO frequency operation from 16 to 30 GHz and IF bandwidth from DC to 8 GHz. It delivers typical conversion loss of 9.5 dB, LO-to-RF isolation of 40 dB, input IP3 of +20 dBm, and requires no DC bias or external matching components. It is used in high-frequency up/downconversion stages of millimeter-wave radios and test instrumentation.
For engineers reviewing the HMC292LC3BTR datasheet, HMC292LC3BTR pinout, HMC292LC3BTR application, or HMC292LC3BTR equivalent, key selection criteria include its 16–30 GHz RF/LO range, DC–8 GHz IF bandwidth, 12-lead ceramic 3×3 mm SMT package, robust Class 1C ESD rating, and compatibility with surface-mount manufacturing without wire bonding.
Technical Context
The HMC292LC3BTR implements a fundamental passive double-balanced architecture using optimized on-chip balun structures to achieve high LO-to-RF and LO-to-IF suppression. Its monolithic GaAs construction enables broadband operation across two RF sub-bands: 16–26 GHz and 26–30 GHz.
It operates with LO drive levels from +9 dBm to +15 dBm, exhibits stable conversion gain vs. temperature (−40°C to +85°C), and supports both upconverter and downconverter configurations without external biasing or tuning components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP3E | Wider RF range (10–40 GHz), higher conversion loss (11.5 dB typ.), same 3×3 mm package | Better suited for multi-band test equipment covering X/Ku/Ka bands; less optimal for narrowband 24 GHz radios | Select when broader RF coverage outweighs 2 dB conversion loss penalty |
| QPC1006 | Higher IF bandwidth (DC–12 GHz), +22 dBm IP3, but requires +17 dBm LO drive and larger 4×4 mm package | Targeted at high-dynamic-range 5G FR2 and automotive radar; not drop-in due to footprint and LO drive mismatch | Choose for enhanced linearity and IF bandwidth where LO power and board space permit |
Compared with HMC292LC3BTR, HMC1048LP3E offers wider RF coverage at the cost of conversion efficiency, while QPC1006 delivers superior linearity and IF bandwidth but demands higher LO power and occupies more PCB area-making HMC292LC3BTR optimal for compact, moderate-dynamic-range 24 GHz radio designs.

FAQ
What is the recommended LO drive level for optimal performance of the HMC292LC3BTR?
The HMC292LC3BTR achieves best conversion loss and isolation with LO drive between +11 dBm and +13 dBm. At +13 dBm, typical conversion loss is 9.5 dB and LO-to-RF isolation reaches 40 dB. Operation below +9 dBm degrades conversion loss and increases distortion; above +15 dBm risks exceeding absolute maximum ratings. The HMC292LC3BTR does not require DC bias, simplifying LO driver stage design.
Can the HMC292LC3BTR be used for DC-coupled IF operation?
Yes, the HMC292LC3BTR supports true DC-coupled IF operation via Pin 5, provided the net DC current sourced or sunk does not exceed ±2 mA. Exceeding this limit may cause non-function or permanent damage. For AC-coupled applications, a series capacitor sized for the lowest IF frequency (e.g., ≥100 pF for 1 GHz) is recommended. The HMC292LC3BTR's DC–8 GHz IF bandwidth makes it suitable for zero-IF and low-IF architectures.
What grounding requirements apply to the HMC292LC3BTR's exposed paddle and GND pins?
The HMC292LC3BTR's exposed ground paddle and Pins 1, 3, 4, 6, 7, and 9 must be soldered directly to a low-inductance RF ground plane using multiple thermal vias. Per the datasheet, failure to connect the paddle compromises thermal dissipation (θJG = 250 °C/W) and RF performance, especially LO-to-RF isolation. The HMC292LC3BTR's 12-lead ceramic package relies on this grounding scheme for repeatable 16–30 GHz behavior.
Does the HMC292LC3BTR support both upconversion and downconversion?
Yes, the HMC292LC3BTR is a bidirectional passive double-balanced mixer and functions identically as an upconverter or downconverter. In upconversion mode, IF is applied to Pin 5 and RF appears at Pin 8; in downconversion, RF enters Pin 8 and IF exits Pin 5. LO is always applied to Pin 2. The HMC292LC3BTR requires no configuration change or external circuit modification between modes.
What is the maximum RF/IF input power rating for the HMC292LC3BTR?
The absolute maximum RF/IF input power for the HMC292LC3BTR is +13 dBm. This limit applies regardless of whether the port is used as RF input, IF output, or IF input in upconversion. Exceeding +13 dBm risks permanent degradation of conversion loss, isolation, or IP3. The HMC292LC3BTR's +20 dBm input IP3 is measured at lower input powers (−10 dBm per tone); sustained operation near +13 dBm should account for thermal derating above 85 °C ambient.
