Product details
Overview
HMC1048ALC3B from Analog Devices is a passive, monolithic microwave integrated circuit (MMIC) double-balanced downconverter operating from 2.25 GHz to 18 GHz at RF, dc to 4 GHz at IF, with typical conversion loss of 14 dB, input IP3 of 20 dBm, and LO-to-RF isolation of 25 dB - deployed in Ka-band transponders and military radar front-ends.
For engineers reviewing the HMC1048ALC3B datasheet, HMC1048ALC3B pinout, HMC1048ALC3B application, or HMC1048ALC3B equivalent, this page delivers verified RF mixer specifications, thermal and isolation performance across frequency bands, surface-mount package constraints, and real-world evaluation board integration guidance for high-frequency downconversion design.
Technical Context
The HMC1048ALC3B implements a passive double-balanced diode ring topology with no DC bias required, enabling operation across two RF bands: 2.25–12 GHz and 12–18 GHz. Its internal ac-coupling on LO and RF ports and dc-coupling on IF port support direct-coupled IF interfaces up to 4 GHz while maintaining >25 dB LO-to-RF isolation.
Thermal management relies on the exposed pad connected to PCB ground, with θJA = 120°C/W under natural convection. Performance remains stable over −40°C to +85°C, with conversion loss variation <2 dB across temperature and LO drive levels from 9 dBm to 17 dBm.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 2.25 GHz to 18 GHz - supports Ka-band and extended X/Ku-band downconversion without external tuning. |
| IF Frequency Range | DC to 4 GHz - enables baseband and wideband IF output, including zero-IF architectures. |
| Conversion Loss | 10–14 dB typical - defines signal attenuation from RF to IF; impacts system noise figure and gain budget. |
| Input IP3 | 20 dBm typical - determines linearity headroom for multi-tone interference rejection in dense RF environments. |
| LO-to-RF Isolation | 25 dB typical - suppresses LO leakage into antenna paths, critical for receiver dynamic range. |
| LO Drive Level | 9–17 dBm - specifies required local oscillator power; lower end reduces LO amplifier complexity. |
| Package | 3 mm × 3 mm, 12-terminal ceramic LCC (E-12-4) - surface-mount compatible with RF PCBs using coplanar waveguide routing. |
Pinout & Package
Package: 3 mm × 3 mm, 12-terminal ceramic leadless chip carrier (E-12-4), with exposed thermal pad requiring RF/dc ground connection per JEDEC-compliant layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 7, 9, 10, 12 | GND | RF and DC ground terminals - must be low-inductance connected to PCB ground plane for optimal isolation and thermal dissipation. |
| 2 | LO | Local oscillator input - internally ac-coupled and 50 Ω matched; accepts 9–17 dBm drive without external matching. |
| 4, 6, 11 | NIC | Not internally connected - may be grounded without affecting RF performance or thermal path. |
| 5 | IF | Intermediate frequency output - dc-coupled; supports dc–4 GHz output but limited to ±6 mA current sourcing/sinking. |
| 8 | RF | Radio frequency input - internally ac-coupled and 50 Ω matched; handles RF signals from 2.25–18 GHz. |
| EPAD | Exposed Pad | Thermal and electrical ground - mandatory connection to PCB ground for junction temperature control and RF return path integrity. |
Key Features
| Feature | Design Value |
|---|---|
| No DC bias required | Eliminates external bias networks and decoupling components, reducing BOM count and layout area in high-frequency designs. |
| High LO-to-RF isolation (25 dB) | Minimizes LO radiation into antenna systems, easing EMI compliance and improving receiver blocking immunity. |
| Wide IF bandwidth (dc to 4 GHz) | Supports complex modulation schemes (e.g., QAM, OFDM) and zero-IF architectures without external IF filtering. |
| Surface-mount ceramic LCC package | Enables automated assembly and eliminates wire bonding; compatible with standard reflow profiles (260°C peak). |
| Stable performance over temperature | Conversion loss variation ≤2 dB from −40°C to +85°C - ensures consistent link budget in outdoor/military deployments. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive double-balanced downconverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1113LP5E | Wider RF range (1–20 GHz), higher conversion loss (15.5 dB typ), same 12-pin LCC package. | Better suited for 1–2 GHz legacy systems; less optimal below 2.25 GHz due to degraded match. | Select when broader low-end coverage is needed and 1.5 dB higher loss is acceptable. |
| HMC774ALC3 | Higher IF bandwidth (dc–6 GHz), improved LO-to-IF isolation (28 dB), same RF range and LO drive. | Preferred for wideband digital IF sampling (e.g., 4–6 GHz ADC interfaces); requires tighter LO filtering. | Choose for next-generation test equipment needing extended IF bandwidth beyond 4 GHz. |
Compared with HMC1048ALC3B, HMC1113LP5E extends low-frequency coverage at the cost of conversion efficiency, while HMC774ALC3 trades marginally better isolation and IF bandwidth for increased sensitivity to LO harmonics - making HMC1048ALC3B the balanced choice for Ka-band transponders and military radios where 2.25–18 GHz fidelity and thermal stability are primary.

FAQ
What is the RF frequency range supported by the HMC1048ALC3B?
The HMC1048ALC3B supports RF frequencies from 2.25 GHz to 18 GHz, validated across two sub-bands: 2.25–12 GHz and 12–18 GHz. Performance metrics including conversion loss, IP3, and isolation are specified separately for each band in the official Rev. B datasheet, with no external matching required across the full range.
Does the HMC1048ALC3B require DC bias voltage or current?
No, the HMC1048ALC3B is a passive double-balanced mixer and requires no DC bias. It operates solely on RF and LO signal energy, eliminating the need for bias tees, decoupling capacitors, or regulated power supplies - simplifying system design and improving reliability in high-frequency layouts.
What is the maximum IF frequency and dc-coupling capability of the HMC1048ALC3B?
The HMC1048ALC3B supports IF output from dc to 4 GHz. Its IF port is internally dc-coupled, allowing true baseband operation. However, the absolute maximum sink/source current is ±6 mA - exceeding this may cause die malfunction, so external current limiting or series capacitance is required if dc coupling is not needed.
How is thermal management handled on the HMC1048ALC3B package?
Thermal management relies on the exposed pad (EPAD), which must be soldered directly to a solid RF/dc ground plane on the PCB. With θJA = 120°C/W under natural convection, proper via stitching around the EPAD and ground layers is essential to maintain junction temperature below 175°C, especially at maximum RF/LO power levels.
Can the HMC1048ALC3B be used in both upconverter and downconverter configurations?
The HMC1048ALC3B is characterized and optimized exclusively as a downconverter (RF → IF). While passive mixers can theoretically operate bidirectionally, Analog Devices specifies performance only for downconversion mode - including isolation, conversion loss, and IP3 - and does not guarantee or characterize upconversion behavior for the HMC1048ALC3B.
