Product details
Overview
HMC631LP3E from Analog Devices (formerly Hittite Microwave) is a GaAs HBT vector modulator IC designed for RF predistortion and feed-forward linearization in wireless infrastructure transceivers. It delivers continuous 360° phase control, 40 dB gain range, +35 dBm input IP3, -160 dBm/Hz output noise floor, and operates across 1.8–2.7 GHz with 200 MHz control bandwidth.
For engineers reviewing the HMC631LP3E datasheet, HMC631LP3E pinout, HMC631LP3E application, or HMC631LP3E equivalent, this device is selected for high-dynamic-range amplitude/phase correction in cellular base station HPAs, beam-forming arrays, and WiMAX MCPA error correction circuits where modulation fidelity and wideband linearity are critical.
Technical Context
The HMC631LP3E implements a dual-path I/Q vector modulator architecture using GaAs HBT technology to enable simultaneous, independent control of RF signal amplitude and phase via analog voltage inputs. Its differential 100 Ω RF input interface and single-ended 50 Ω RF output support integration into balanced front-end designs without external baluns beyond the integrated input balun (0.8 dB loss).
Control ports exhibit 1.45 kΩ impedance and 0.22 pF capacitance, enabling stable DC-coupled voltage drive from DACs or op-amps across the +0.5 V to +2.5 V range. The device achieves 20 ps group delay variation over any 60 MHz bandwidth and maintains gain flatness within ±0.4 dB - critical for wideband digital predistortion (DPD) loop stability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar vector modulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC630LP3E | Narrower frequency range (1.7–2.2 GHz); 35 dB gain range; -158 dBm/Hz noise floor. | Better suited for lower-band LTE (Band 3/7) where extended upper-band coverage is unnecessary. | Select when operating exclusively below 2.2 GHz and lower cost or reduced thermal load is prioritized. |
| ADL5375-05 | SiGe-based; 0.7–1.0 GHz range; integrated LO buffer; requires external IF filtering; +29 dBm OIP3. | Targeted at IF-stage vector modulation in broadband receivers, not direct RF-band correction. | Choose for sub-1 GHz infrastructure or test equipment requiring integrated LO distribution and lower supply current. |
Compared with HMC631LP3E, HMC630LP3E offers narrower bandwidth but lower power consumption, while ADL5375-05 targets lower-frequency IF modulation with integrated LO functionality - neither is pin-compatible, and both require layout adaptation for RF path integration.

FAQ
What is the operating frequency range of the HMC631LP3E?
The HMC631LP3E operates from 1.8 GHz to 2.7 GHz, covering key cellular bands including LTE Bands 1, 3, 7, 38, 40, and 41, as well as WiMAX 2.3/2.5/2.6 GHz allocations. Performance is specified across two sub-bands: 1.8–2.2 GHz and 2.2–2.7 GHz, with consistent gain flatness and return loss maintained throughout.
Does the HMC631LP3E require external baluns for RF interfacing?
The HMC631LP3E integrates an input balun with 0.8 dB typical insertion loss, enabling direct connection to differential RF sources without external components. Its differential RF input (pins 2 and 3) presents 100 Ω impedance (50 Ω each to ground), and the single-ended RF output (pin 9) is 50 Ω - only DC blocking capacitors are required on both sides.
What is the recommended supply voltage and current for the HMC631LP3E?
The HMC631LP3E is specified for +8 V DC supply, drawing 93 mA at that voltage and room temperature. Absolute maximum supply voltage is +10 V. Supply current varies linearly: 88 mA at +7.6 V and 99 mA at +8.4 V. All four Vcc pins (7, 8, 13, 14) must be bypassed to ground with low-ESR capacitors.
How does the HMC631LP3E achieve 360° phase control?
The HMC631LP3E uses dual analog control voltages applied to redundant I (pins 5/15) and Q (pins 6/16) inputs, each ranging from +0.5 V to +2.5 V. Phase is calculated as θ = arctan(VQ/VI), enabling continuous 360° coverage. The internal GaAs HBT core translates these voltages into precise vector summation of I and Q signal paths.
Is the HMC631LP3E RoHS-compliant?
Yes, the HMC631LP3E is RoHS-compliant, featuring a low-stress injection-molded plastic body with 100% matte tin lead finish and MSL1 moisture sensitivity rating (260 °C peak reflow). This distinguishes it from the non-RoHS HMC631LP3 variant, which uses Sn/Pb solder finish.
