Product details
Overview
HMC904LC5 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC I/Q downconverter IC for RF front-end signal processing in 17–24 GHz systems. It delivers 12 dB small-signal conversion gain, 3 dB noise figure, and 30 dB image rejection with 160–190 mA supply current at 3.5 Vdc. Used in satellite communications receivers and military radar IF chains where compact, high-rejection downconversion is required.
For engineers reviewing the HMC904LC5 datasheet, HMC904LC5 pinout, HMC904LC5 application, or HMC904LC5 equivalent, this page provides verified RF performance data, thermal and isolation specs, package layout details, and validated alternatives for Ka-band receiver design and EW system integration.
Technical Context
The HMC904LC5 integrates an RF LNA followed by an image-reject mixer driven by an active x2 LO multiplier, eliminating the need for external image-filtering after amplification. Its architecture enables direct IF output of quadrature baseband signals without internal 90° hybrid - requiring only an external IF hybrid to select USB or LSB.
It operates across dual RF bands (17–20 GHz and 20–24 GHz), with corresponding LO ranges (7.5–11.75 GHz and 8.25–12.3 GHz), supporting flexible frequency planning. All RF, LO, and IF ports are 50 Ω matched, AC-coupled (RF/LO) or DC-coupled (IF1/IF2), with strict grounding requirements on 32-pin 5×5 mm SMT package leads and exposed paddle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 17–24 GHz (dual-band operation supports Ka-band point-to-point radio and SATCOM uplinks/downlinks) |
| Conversion Gain | 12 dB typical (enables single-stage downconversion without cascaded gain stages in sensitive receiver chains) |
| Noise Figure | 3 dB typical (low-noise front-end capability preserves SNR in high-frequency radar and ELINT applications) |
| Image Rejection | 30 dB typical (reduces need for external image-reject filtering, simplifying IF path design) |
| LO to RF Isolation | 45 dB typical (minimizes LO leakage into antenna path, critical for full-duplex and TDD systems) |
| Supply Current | 160–190 mA at 3.5 Vdc (defines thermal load and PCB power delivery requirements for compact SMT layouts) |
| Input IP3 | 0 dBm typical (sets linearity limit for handling strong interferers in dense spectral environments) |
Pinout & Package
32-lead 5×5 mm leadless RoHS-compliant SMT package with alumina body, gold-over-nickel plating, and exposed ground paddle requiring solder connection to PCB RF ground plane. MSL3 rating; max reflow peak 260 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 7, 30 | Power/RF/LO Supply Inputs | VDLO (pin 1), VDLO2 (pin 3), VDRF (pin 7), LO (pin 30) - require local decoupling and stable biasing per RF stage |
| 11 | RF Input | AC-coupled 50 Ω matched port; connects directly to antenna or filter output in Ka-band front-end |

| 10, 19, 24, 29 | Ground Terminals | Must be connected to RF/DC ground; used with exposed paddle for optimal thermal and RF return path |
| 2, 4–6, 8, 9, 12–18, 21, 22, 25–28, 31, 32 | No-Connect | Internally unconnected but externally grounded per measurement setup to maintain RF integrity |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar I/Q downconverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1040LP5E | Wider RF range (13–25 GHz), lower conversion gain (9 dB), higher supply current (220 mA) | Better suited for ultra-wideband scanning receivers; less ideal for gain-constrained low-SNR radar paths | Select when broader frequency coverage outweighs gain and power trade-offs |
| ADMV1013ACPZ | Integrated LO synthesizer and digital SPI interface; 24–44 GHz RF range; requires external LO for HMC904LC5's 17–24 GHz band | Targeted at fully integrated microwave transceivers; not drop-in for legacy LO-driven designs | Choose for new designs needing programmable LO and calibration features, not for HMC904LC5 replacement |
Compared with HMC1040LP5E and ADMV1013ACPZ, the HMC904LC5 offers superior conversion gain and lower power consumption within its native 17–24 GHz band, making it optimal for space-constrained, high-efficiency Ka-band receiver modules where external LO control is already established.

FAQ
What is the recommended LO drive level for optimal performance of the HMC904LC5?
The HMC904LC5 is characterized at +4 dBm LO drive, delivering 12 dB conversion gain and 30 dB image rejection. Performance degrades below +2 dBm or above +8 dBm - gain compresses and IP3 drops. For stable operation, maintain LO drive between +3 dBm and +5 dBm using calibrated source or buffer amplifier. The HMC904LC5 does not include internal LO buffering, so external level control is essential.
Does the HMC904LC5 require an external 90° hybrid, and why?
Yes, the HMC904LC5 requires an external IF 90° hybrid to combine IF1 and IF2 outputs and select either upper or lower sideband. The device outputs true I/Q signals without internal phase shifting; the hybrid enables sideband suppression and flexible demodulation. Without it, the HMC904LC5 functions as a standard double-balanced mixer with no image rejection - defeating its core architecture advantage.
What are the absolute maximum ratings for RF and LO input power on the HMC904LC5?
The HMC904LC5 has absolute maximum ratings of +2 dBm for RF input and +10 dBm for LO drive. Exceeding +2 dBm RF risks compression and distortion; exceeding +10 dBm LO may damage the internal x2 multiplier. For reliable operation, keep RF input ≤ –10 dBm (small-signal region) and LO drive at +4 dBm ±1 dB. Thermal derating applies above 85°C ambient.
How should the exposed ground paddle on the HMC904LC5 package be handled in PCB layout?
The exposed ground paddle on the HMC904LC5 must be soldered to a solid RF ground plane using multiple thermal vias (≥8, 0.3 mm diameter) spaced ≤1 mm apart. This ensures both thermal dissipation (RTH = 53.2 °C/W) and RF return path integrity. Floating or poorly connected paddle causes degraded isolation, increased noise figure, and potential instability - especially above 18 GHz.
Can the HMC904LC5 operate down to DC on its IF outputs, and what are the current limits?
Yes, the HMC904LC5 IF1 and IF2 outputs are DC-coupled and support operation from DC to 3.5 GHz. However, each IF pin must not sink or source more than ±3 mA - exceeding this causes non-function or permanent damage. For DC-coupled use, ensure downstream circuitry presents high-impedance load or includes current-limiting bias networks. AC coupling is recommended for AC-only applications to avoid violating current limits.
