Product details
Overview
HMC496LP3ETR from Analog Devices (formerly Hittite Microwave) is a SiGe wideband direct quadrature modulator RFIC designed for RF upconversion in 4–7 GHz systems. It delivers +2 dBm RF output power, -157 dBm/Hz noise floor, and 34 dBc uncalibrated carrier suppression with +3 V @ 93 mA supply. Used in C-band microwave radios and 802.11a WLAN transmitters.
For engineers reviewing the HMC496LP3ETR datasheet, HMC496LP3ETR pinout, HMC496LP3ETR application, or HMC496LP3ETR equivalent, key selection criteria include its 4–7 GHz RF bandwidth, differential/single-ended LO drive flexibility, DC–250 MHz baseband input range, and 3×3 mm QFN package compatibility with high-density RF layouts.
Technical Context
The HMC496LP3ETR implements a SiGe-based direct-conversion quadrature modulator architecture with fully differential I/Q baseband inputs (IP/IN, QP/QN), differential or single-ended LO interface (LOP/LON), and matched 50 Ω differential RF output (RFP/RFN). Its internal biasing supports DC-coupled baseband operation with user-adjustable Vbbdc (1.0–1.6 V) to optimize carrier suppression across temperature and frequency.
It operates over -40 °C to +85 °C with supply voltage tolerance of 2.7–3.3 V, requires no external matching on RF port, and achieves calibrated sideband suppression >40 dBc at 5.2 GHz with manual I/Q amplitude/phase tuning. LO input power range is -3 to +6 dBm, enabling compatibility with low-power synthesizers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 4.0–7.0 GHz - Supports full C-band and U-NII-3 spectrum without band switching. |
| Output Noise Floor | -157 dBm/Hz typical - Enables high SNR in wideband digital modulation (e.g., 64-QAM). |
| Carrier Suppression | 34 dBc uncalibrated - Reduces LO leakage impact on adjacent channel interference without calibration circuitry. |
| LO Input Power | -3 to +6 dBm - Compatible with integrated PLL/VCOs and eliminates need for external LO amplification. |
| Baseband Bandwidth | DC–250 MHz - Supports 200 MHz signal bandwidths required for IEEE 802.11ac/ax OFDM waveforms. |
| Supply Voltage & Current | +3.0 V @ 93 mA - Low-power operation suitable for compact, thermally constrained RF front-ends. |
| Package | 3×3 mm QFN-16 - Exposed paddle enables efficient thermal dissipation; MSL1 rating supports standard reflow. |
Pinout & Package
Package: 3×3 mm, 16-lead QFN with exposed thermal paddle (MSL1, RoHS-compliant matte Sn finish). Ground paddle and pins 1/4/9/12 must be soldered to PCB RF ground plane using multiple vias for optimal thermal and RF performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | GND | RF/DC ground reference; connects to exposed paddle - critical for return path integrity and noise rejection. |
| 2, 3 | LOP, LON | Differential LO input - accepts single-ended drive (one pin terminated 50 Ω) or true differential LO for improved common-mode rejection. |
| 5, 8, 13 | N/C | No internal connection - may be grounded without affecting RF performance or thermal path. |
| 6, 7 | QN, QP | Differential Q-baseband input - high-impedance; DC bias (1.2–1.4 V) tunes carrier suppression; 1.2 Vpp diff drives quadrature modulation. |
| 10, 11 | RFN, RFP | Differential RF output - internally matched to 50 Ω; series AC-coupling capacitor required to block VCC. |
| 14, 15 | IP, IN | Differential I-baseband input - identical electrical behavior to Q inputs; independent DC bias enables I/Q offset correction. |
| 16 | VCC | +3.0 V supply input - draws 93 mA nominal; decoupling with 100 pF (RF) and 4.7 µF (bulk) recommended per eval board. |
Key Features
| Feature | Design Value |
|---|---|
| Wideband RF operation | 4–7 GHz continuous coverage - eliminates need for multiple narrowband modulators in multi-standard radios. |
| Low-noise floor | -157 dBm/Hz typical - preserves EVM in high-order QAM by minimizing added noise in signal chain. |
| Flexible LO drive | Supports -3 to +6 dBm differential or single-ended - simplifies LO path design and reduces BOM count. |
| User-tunable I/Q offsets | Adjustable Vbbdc (1.0–1.6 V) on IP/IN/QP/QN - enables factory or system-level carrier/sideband suppression optimization. |
| Integrated 50 Ω RF match | No external matching components required on RF output - reduces layout area and parasitic sensitivity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar direct quadrature modulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADL5375-05 | 5.0–6.0 GHz RF range; higher 100 mA supply current; requires external LO buffer. | Limited to 5–6 GHz band; less flexible for full 4–7 GHz coverage. | Prefer HMC496LP3ETR when full C-band/U-NII coverage or lower power is required. |
| HMC6301LP3E | 24–44 GHz operation; GaAs process; 5.0 V supply; 120 mA current. | Targeted at E-band mmWave, not sub-6 GHz infrastructure. | Not interchangeable - HMC496LP3ETR is sole option for 4–7 GHz SiGe modulator with MSL1 QFN packaging. |

FAQ
What is the RF frequency range supported by the HMC496LP3ETR?
The HMC496LP3ETR supports a continuous RF frequency range of 4.0–7.0 GHz, covering U-NII-1/2C/3 bands, C-band microwave links (5.925–6.425 GHz), and WLL allocations. Performance metrics including output power, IP3, and noise floor are specified across this full range, with no band-switching circuitry required.
Does the HMC496LP3ETR require external RF matching components?
No. The HMC496LP3ETR features an internally matched 50 Ω differential RF output (pins 10/11), eliminating the need for external baluns, matching networks, or tuning stubs. A series AC-coupling capacitor is required to block VCC from the RF path, but no impedance transformation is necessary.
Can the HMC496LP3ETR operate with single-ended LO drive?
Yes. The HMC496LP3ETR accepts both differential (LOP/LON) and single-ended LO input. In single-ended mode, one LO pin is driven while the other is terminated with a 50 Ω resistor to ground. This flexibility simplifies integration with non-differential LO sources such as integer-N PLLs.
What is the baseband input bandwidth of the HMC496LP3ETR?
The HMC496LP3ETR supports a baseband input bandwidth of DC to 250 MHz typical, achieved using 10 pF shunt capacitors per I/Q path as shown in the evaluation schematic. This enables support for 200 MHz OFDM signals used in WiGig and high-throughput 802.11ac/ax implementations.
How is carrier suppression optimized in the HMC496LP3ETR?
Carrier suppression in the HMC496LP3ETR is optimized by adjusting the DC bias voltage (Vbbdc) applied to the I and Q differential baseband inputs (pins 14/15 and 6/7). The recommended range is 1.0–1.6 V, with 1.3 V nominal; fine-tuning within ±15 mV enables >34 dBc uncalibrated suppression across temperature and frequency.
