Product details
Overview
HMC1048LC3BTR-R5 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC double-balanced passive mixer for RF-to-IF downconversion, operating 2–18 GHz at RF/LO ports and DC–4 GHz at IF port, with 11 dB typical conversion loss, +23 dBm input IP3, and no DC bias required. It serves in Ka-band transponders, point-to-multipoint radios, and military test equipment.
For engineers reviewing the HMC1048LC3BTR-R5 datasheet, HMC1048LC3BTR-R5 pinout, HMC1048LC3BTR-R5 application, or HMC1048LC3BTR-R5 equivalent, key selection criteria include LO drive range (+9 to +17 dBm), RF/IF isolation performance, ceramic 3×3 mm SMT package compatibility, and DC-coupled IF interface requirements.
Technical Context
This passive diode-based double-balanced mixer uses GaAs Schottky barrier technology and operates without DC bias or external matching components. Its balanced topology suppresses even-order harmonics and provides inherent LO–RF, LO–IF, and RF–IF isolation.
It supports both downconverter and upconverter configurations, with spurious output data confirmed across M×N mixing products (e.g., 2LO−1RF at −2.4 dBc). Performance is characterized over −55°C to +85°C with LO drive levels from +9 dBm to +17 dBm.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 2–18 GHz - Enables coverage from S-band through K-band in single device. |
| IF Bandwidth | DC–4 GHz - Supports baseband and wideband IF outputs without AC coupling constraints. |
| Conversion Loss | 11 dB typ. - Defines signal attenuation from RF to IF path; impacts system noise figure budget. |
| Input IP3 | +23 dBm typ. - Determines third-order intermodulation distortion floor in multi-tone RF environments. |
| LO/RF Isolation | 38 dB typ. - Reduces LO leakage into antenna or RF front-end, easing filtering requirements. |
| LO Drive Level | +9 to +17 dBm - Specifies required LO power range for optimal linearity and conversion efficiency. |
| Operating Temperature | −55°C to +85°C - Qualified for extended industrial and military environmental operation. |
Pinout & Package
12-lead ceramic 3 × 3 mm surface-mount package (9 mm² footprint) with exposed ground paddle; RoHS-compliant, gold-over-nickel finish, MSL3 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 7, 9, 10, 12 | GND | RF/DC ground connections; must be low-inductance tied to PCB ground plane and exposed paddle. |
| 2 | LO | 50 Ω matched RF input for local oscillator signal; requires stable +9 to +17 dBm drive. |
| 4, 6, 11 | N/C | No internal connection; datasheet specifies all measurements taken with these pins grounded. |
| 5 | IF | DC-coupled 50 Ω IF output; enables baseband and low-IF architectures without blocking capacitors. |
| 8 | RF | 50 Ω matched RF input/output port; supports bidirectional use in up/downconverter topologies. |

|---|---|
| No DC bias required | Eliminates external power supply and decoupling network, reducing BOM count and board space. |
| High LO/RF isolation (38 dB) | Minimizes LO radiation into RF path, lowering risk of self-jamming in full-duplex systems. |
| DC–4 GHz IF bandwidth | Supports zero-IF and low-IF receivers with direct sampling ADCs or analog baseband processing. |
| 12-lead ceramic SMT package | Enables automated assembly and repeatable RF performance vs. wire-bonded alternatives. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1113LP3DE | 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 18 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; 15 dB gain; 18–44 GHz RF range. | Provides gain instead of loss; targets E-band systems where signal amplification precedes digitization. | Choose only if system architecture requires IF gain and can accommodate active biasing and higher power consumption. |
Compared with HMC1048LC3BTR-R5, HMC1113LP3DE trades Ka-band isolation for sub-2 GHz extension, while QPC1006 shifts from passive loss to active gain-requiring redesign of bias, thermal, and noise management in the signal chain.

FAQ
What is the recommended LO drive level for optimal performance of the HMC1048LC3BTR-R5?
The HMC1048LC3BTR-R5 achieves best conversion loss and IP3 performance with LO drive between +13 dBm and +15 dBm. At +13 dBm, typical conversion loss is 11 dB and input IP3 is +23 dBm. Operation below +9 dBm or above +17 dBm degrades linearity and may cause compression or reliability concerns. The HMC1048LC3BTR-R5 datasheet specifies this range under TA = +25°C, downconverter configuration with IF = 100 MHz.
Does the HMC1048LC3BTR-R5 support upconverter operation?
Yes, the HMC1048LC3BTR-R5 supports upconversion with confirmed M×N spurious data for both downconverter and upconverter modes. In upconverter testing (e.g., RF = 4 GHz, LO = 4.1 GHz), spurs such as 1LO+1IF appear at −10.3 dBc. The HMC1048LC3BTR-R5's passive architecture and symmetric port design enable bidirectional use, though IF port DC coupling remains fixed.
Is the HMC1048LC3BTR-R5 pin-compatible with other Hittite 3×3 mm mixer variants?
No documented pin-compatible replacement exists for the HMC1048LC3BTR-R5 within the Hittite/Analog Devices portfolio. Pin functions (e.g., LO on Pin 2, RF on Pin 8, IF on Pin 5) are specific to this variant; alternate mixers like HMC1113LP3DE share the 3×3 mm outline but differ in internal routing and pin assignment. The HMC1048LC3BTR-R5 pinout must be verified against layout footprints before substitution.
What is the thermal resistance and maximum junction temperature of the HMC1048LC3BTR-R5?
The HMC1048LC3BTR-R5 has a thermal resistance (RTH) of 392 °C/W (junction to package bottom) and a maximum junction temperature of 116 °C at TA = 85 °C with +19 dBm LO drive. Continuous power dissipation is rated at 165 mW at 85 °C, derating by 2.5 mW/°C above that temperature. These values are critical for thermal pad design and airflow planning in enclosed RF modules containing the HMC1048LC3BTR-R5.
Can the HMC1048LC3BTR-R5 be used with AC-coupled IF interfaces?
The HMC1048LC3BTR-R5 IF port is DC-coupled and internally biased for direct connection to 50 Ω systems; AC coupling is not required but may be added externally if DC blocking is needed for downstream stages. Inserting series capacitors will attenuate sub-100 MHz IF content and must be modeled for impedance discontinuity. The HMC1048LC3BTR-R5's specified IF bandwidth (DC–4 GHz) assumes direct 50 Ω termination without AC coupling.
