Analog Devices Inc. EV1HMC648ALP6

Overview

EV1HMC648ALP6 from Analog Devices is a GaAs MMIC 6-bit digital phase shifter operating from 2.9 to 3.9 GHz, delivering 360° phase coverage with 5.625° LSB resolution, 1.2° RMS phase error, ±0.5 dB insertion loss variation, and 50 Ω internal matching-used in radar beamforming and satellite communications front-ends.

For engineers reviewing the EV1HMC648ALP6 datasheet, EV1HMC648ALP6 pinout, EV1HMC648ALP6 application, or EV1HMC648ALP6 equivalent, key selection criteria include frequency band alignment (2.9–3.9 GHz), low RMS phase error (<1.5°), insertion loss stability (±0.5 dB), control logic compatibility (0/+5 V), and 28-pin 6×6 mm QFN package thermal and RF grounding requirements.

Technical Context

The EV1HMC648ALP6 implements a monolithic GaAs-based switched-line architecture with six independent bit-controlled phase paths, enabling monotonic 6-bit state selection per truth table. It operates with dual supply rails (Vdd = +5 V, Vss = −5 V) and requires no external matching components due to on-die 50 Ω termination at both RFIN and RFOUT.

Phase and amplitude settling are optimized for fast T/R switching: phase settles within 125 ns (±1°), amplitude within 175 ns (±0.1 dB). Bias current draw is 5.2 mA per rail, and control inputs draw ≤250 µA at +5 V, supporting TTL/CMOS-compatible digital interface timing.

Key Specifications

FAQ

What is the operating frequency range of the EV1HMC648ALP6?

The EV1HMC648ALP6 operates from 2.9 GHz to 3.9 GHz with fully characterized performance-including RMS phase error, insertion loss variation, and return loss-across this entire X-band sub-range. All specifications in the datasheet apply within this band under standard bias conditions (Vdd = +5 V, Vss = −5 V, TA = +25°C).

Does the EV1HMC648ALP6 require external matching components?

No, the EV1HMC648ALP6 features internal 50 Ω matching at both RFIN and RFOUT ports, eliminating the need for external matching networks. This simplifies PCB layout and improves repeatability in high-frequency designs-verified across all 64 phase states and the full 2.9–3.9 GHz band per Analog Devices' characterization data.

What is the phase resolution and total coverage of the EV1HMC648ALP6?

The EV1HMC648ALP6 provides 6-bit digital control with 5.625° least significant bit (LSB) resolution, delivering 360° of total phase coverage across 64 discrete states. The truth table confirms monotonic behavior, and measurements show phase error remains within ±15° (max) and 1.2° (RMS) across all states and frequencies.

How is the EV1HMC648ALP6 controlled-voltage levels and current draw?

The EV1HMC648ALP6 uses positive 0/+5 V control logic: "Low" = 0–0.2 Vdc, "High" = Vdd ±0.2 Vdc. Each BIT input draws ≤250 µA at +5 V. Vdd and Vss each draw 5.2 mA at nominal bias, and the device supports TTL/CMOS-compatible digital drivers without level shifting.

What package type and grounding requirements does the EV1HMC648ALP6 have?

The EV1HMC648ALP6 uses a 28-lead 6×6 mm plastic leadless package (QFN) with exposed ground paddle. Pins 2 and 20 plus the paddle must be soldered to a solid RF ground plane using multiple thermal vias. This configuration is mandatory to meet specified RF performance, thermal resistance (120 °C/W), and ESD robustness (Class 1A, 250 V HBM).
