Product details
Overview
HMC1048LC3BTR from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC double-balanced mixer designed for RF-to-IF downconversion in 2–18 GHz systems. It delivers 11 dB typical conversion loss, +23 dBm input IP3, and operates with LO drive from +9 to +17 dBm across DC–4 GHz IF bandwidth - enabling Ka-band transponder and point-to-multipoint radio front-ends without external matching.
For engineers reviewing the HMC1048LC3BTR datasheet, HMC1048LC3BTR pinout, HMC1048LC3BTR application, or HMC1048LC3BTR equivalent, key selection criteria include its passive architecture (no DC bias), 12-lead 3×3 mm ceramic SMT package, LO/RF isolation ≥38 dB, and compatibility with surface-mount manufacturing for high-frequency test equipment and military radios.
Technical Context
The HMC1048LC3BTR implements a passive diode-ring topology with balanced LO and RF ports, eliminating DC bias requirements and enabling wideband operation from 2 to 18 GHz RF and DC to 4 GHz IF. Its monolithic GaAs construction ensures stable performance across –55°C to +85°C operating temperature.
It supports both downconverter and upconverter configurations, with spurious output data confirmed for M×N mixing products (e.g., 2LO±RF, 3LO±2RF) at ≤–20 dBc under specified drive conditions. LO drive sensitivity is optimized for +13 dBm nominal operation, delivering consistent conversion gain and IP3 across temperature and frequency sweeps.

Equivalent & Alternatives
The following parts are listed as comparable options for similar double-balanced mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1113LP3E | Wider RF range (1–20 GHz), higher conversion loss (13 dB typ.), same 3×3 mm package. | Better suited for 1–2 GHz legacy radar bands; less optimal for Ka-band due to degraded isolation above 15 GHz. | Select when broader low-end coverage is needed and Ka-band performance margin is acceptable. |
| QPC1006 | GaAs pHEMT-based active mixer; requires +5 V bias; 17 dB conversion gain; 10–16 GHz RF range. | Provides gain instead of loss, but adds power supply, noise, and linearity trade-offs; narrower band than HMC1048LC3BTR. | Choose only if system-level gain budget is constrained and LO power is limited; not drop-in compatible. |
Compared with HMC1113LP3E and QPC1006, the HMC1048LC3BTR offers superior Ka-band linearity and isolation without bias, making it optimal for unpowered, wideband downconversion where thermal stability and LO leakage control are critical.

FAQ
What is the recommended LO drive level for optimal performance of the HMC1048LC3BTR?
The HMC1048LC3BTR achieves best conversion loss, IP3, and isolation at +13 dBm LO drive. Performance remains functional across +9 to +17 dBm, but deviation increases conversion loss by up to 2 dB and reduces IP3 by ~3 dB outside ±2 dB of nominal. The HMC1048LC3BTR does not require regulation or leveling circuitry at these drive levels.
Does the HMC1048LC3BTR support upconversion as well as downconversion?
Yes, the HMC1048LC3BTR supports both downconversion (RF→IF) and upconversion (IF→RF) modes. Spurious output data is documented for M×N products in both configurations, including 2LO±RF and LO±2RF terms measured at ≤–20 dBc. The HMC1048LC3BTR requires identical 50 Ω terminations on all ports regardless of mode.
Is external matching required when using the HMC1048LC3BTR?
No external matching is required. All ports (LO, RF, IF) are internally matched to 50 Ω across their full operating bands. The HMC1048LC3BTR is designed for direct integration into 50 Ω microstrip layouts, with ground pins and exposed paddle providing return path integrity - confirmed in Hittite's EVAL01-HMC1048LC3B reference design.
What is the thermal resistance and maximum power dissipation of the HMC1048LC3BTR?
The HMC1048LC3BTR has a junction-to-package-bottom thermal resistance (RTH) of 392 °C/W. At TA = 85 °C, maximum continuous power dissipation is 165 mW, derating linearly by 2.5 mW/°C above that temperature. The exposed ground paddle must be soldered to a thermally robust ground plane to achieve this rating - verified in the HMC1048LC3BTR absolute maximum ratings table.
Can the HMC1048LC3BTR be used in DC-coupled IF applications?
Yes, the IF port (Pin 5) is DC-coupled and 50 Ω matched, enabling direct connection to baseband ADCs or analog processors without blocking capacitors. This feature is explicitly validated in electrical specifications for IF = DC–4 GHz operation and confirmed in application schematics for test equipment and radar receivers using the HMC1048LC3BTR.
