Product details
Overview
HMC496LP3E 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. Its 3×3 mm QFN package supports compact microwave radio and WLAN transmitters requiring low-LO-power, single-supply operation.
For engineers reviewing the HMC496LP3E datasheet, HMC496LP3E pinout, HMC496LP3E application, or HMC496LP3E equivalent, this page provides verified technical context, calibrated vs. uncalibrated suppression behavior, baseband bias optimization guidance, LO drive flexibility (differential or single-ended), and real-world performance across temperature and supply voltage variations.
Technical Context
The HMC496LP3E implements a SiGe-based direct-conversion quadrature modulator architecture with fully differential I/Q baseband inputs (IP/IN, QP/QN) and differential RF output (RFP/RFN). It operates without external matching on the 50 Ω RF port and accepts LO input from -3 to +6 dBm in either differential or single-ended mode.
Carrier and sideband suppression are tunable via DC bias adjustment on I/Q ports (Vbbdc = 1.0–1.6 V) and amplitude/phase trimming of baseband signals; calibrated suppression reaches 40 dBc sideband and >45 dBc IM3 at 5.2 GHz. Performance is specified over -40 °C to +85 °C with stable 93 mA current draw from 2.7–3.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 4.0–7.0 GHz - Full-band operation without tuning; supports C-band microwave radios and U-NII/WLAN 5 GHz bands. |
| Output Noise Floor | -157 dBm/Hz typical - Enables high dynamic range in wideband receivers and low-error-rate digital modulation. |
| Carrier Suppression | 34 dBc uncalibrated - Reduces DC offset sensitivity; improves EVM in 802.11a and WLL transmitters. |
| LO Input Power | -3 to +6 dBm - Eliminates need for LO buffer amplifiers in cost-sensitive SMT designs. |
| Supply Voltage & Current | +3.0 V @ 93 mA - Single low-current rail simplifies power delivery; compatible with standard 3.3 V LDOs. |
| Baseband Bandwidth | DC–250 MHz - Supports complex modulation schemes (e.g., 64-QAM) with minimal group delay distortion. |
| Package | 3×3 mm QFN-16 - Exposed paddle enhances thermal dissipation; MSL1 rating supports lead-free reflow at 260 °C. |
Pinout & Package
Package: 3×3 mm, 16-pin QFN with exposed thermal paddle (RoHS-compliant matte Sn finish, MSL1, peak reflow 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | GND | RF/DC ground terminals - must connect to PCB ground plane with multiple vias; critical for noise floor and return loss stability. |
| 2, 3 | LOP, LON | Differential LO input - supports single-ended drive (one pin driven, other terminated to 50 Ω); enables flexible LO source integration. |
| 5, 8, 13 | N/C | No connection - may be grounded without performance impact; no internal circuitry attached. |
| 6, 7 | QN, QP | Differential Q baseband input - high-impedance; DC bias (1.2–1.4 V) tunes carrier suppression; 1.2 Vpp differential nominal. |
| 10, 11 | RFN, RFP | Differential RF output - internally matched to 50 Ω; requires series AC-coupling capacitor to block VCC from RF path. |
| 14, 15 | IP, IN | Differential I baseband input - identical biasing and signal requirements as Q channel; independent amplitude/phase trim enables sideband optimization. |
| 16 | VCC | Power supply input - 3.0 V nominal; draws 93 mA; decoupling near pin essential for RF stability. |
Key Features
| Feature | Design Value |
|---|---|
| Wideband 4–7 GHz RF operation | Eliminates band-switching components in multi-standard radios; covers entire U-NII-2/3 and C-band microwave allocations. |

FAQ
What is the RF frequency range supported by the HMC496LP3E?
The HMC496LP3E supports an RF frequency range of 4.0 to 7.0 GHz, covering the full C-band and key U-NII-2/3 and WLAN 5 GHz allocations. This range is validated across temperature and supply voltage variations, with consistent output power and noise floor performance. The HMC496LP3E does not require external tuning components to operate across this band.
Can the HMC496LP3E be driven with a single-ended LO signal?
Yes, the HMC496LP3E accepts single-ended LO drive on either LOP or LON pin while terminating the other to 50 Ω. Its differential LO input architecture allows this flexibility without performance degradation. The HMC496LP3E maintains specified carrier suppression and noise floor when driven with -3 to +6 dBm single-ended LO power, simplifying integration with common VCOs and synthesizers.
How is carrier suppression optimized on the HMC496LP3E?
Carrier suppression on the HMC496LP3E is optimized by adjusting the DC bias voltage (Vbbdc) applied to the I and Q baseband input pairs (IP/IN and QP/QN), typically within 1.0–1.6 V. Fine-tuning this voltage-often to <15 mV offset-improves uncalibrated suppression to 34 dBc. The HMC496LP3E datasheet provides test conditions and calibration procedures for achieving >45 dBc with manual I/Q skew adjustment.
What is the recommended baseband input configuration for the HMC496LP3E?
The HMC496LP3E requires differential baseband inputs (IP/IN and QP/QN) with 1.2 Vpp peak-to-peak swing and DC bias between 1.2–1.4 V. External 10 pF shunt capacitors set the DC–250 MHz bandwidth. The HMC496LP3E's high-impedance inputs simplify interface with DACs or BB processors, and its bias-adjustable architecture enables optimization across temperature and frequency bands.
Does the HMC496LP3E require external RF matching components?
No, the HMC496LP3E's RF output port (RFP/RFN) is internally matched to 50 Ω across 4–7 GHz, eliminating the need for external matching networks. A series AC-coupling capacitor is required to block VCC from the RF path, but no baluns, transformers, or stubs are needed. This feature reduces bill-of-materials cost and PCB area, distinguishing the HMC496LP3E from discrete modulator solutions.
