Analog Devices Inc. EV1HMC881ALP5

Overview

EV1HMC881ALP5 from Analog Devices is an evaluation PCB designed to characterize the HMC881A tunable low-pass filter IC - a monolithic microwave integrated circuit with user-selectable 2.4 GHz to 4 GHz cutoff frequency, 3 dB insertion loss, and 16.5 dB return loss. It supports RF testing in military radar, satellite comms, and electronic warfare systems.

For engineers reviewing the EV1HMC881ALP5 datasheet, EV1HMC881ALP5 pinout, EV1HMC881ALP5 application, or EV1HMC881ALP5 equivalent, this board enables rapid validation of HMC881A's tuning voltage (0–14 V), amplitude settling time (200 ns), wideband rejection (≥35 dB), and temperature-stable f_3dB performance across −40°C to +85°C.

Technical Context

The EV1HMC881ALP5 is a dedicated evaluation platform for the HMC881A MMIC tunable low-pass filter. It implements precise 50 Ω RF routing on Layer 1 using Rogers 4350 top dielectric and Isola 370HR core, with three internal ground planes ensuring stable impedance control and minimal signal loss.

All RF interfaces use SMA connectors (J1/J2 for RFIN/RFOUT, J3 for VFCTL), and includes two 100 pF 0402 DC-blocking capacitors (C1/C2). The board requires direct connection of the HMC881A's exposed pad and GND pins to solid ground via multiple vias, per JEDEC MO-220-WHHD-5 compliant LFCSP-32 layout guidelines.

FAQ

What is the primary function of the EV1HMC881ALP5 evaluation board?

The EV1HMC881ALP5 evaluation board is a dedicated test platform for the HMC881A tunable low-pass filter IC. It enables engineers to validate real-world RF performance - including cutoff frequency tuning (2.4–4 GHz), insertion loss (≤3 dB), return loss (≥16.5 dB), and wideband rejection (≥35 dB) - under controlled 50 Ω conditions using SMA interfaces and calibrated PCB layout.

Does the EV1HMC881ALP5 include the HMC881A IC?

Yes, the EV1HMC881ALP5 includes the HMC881A IC mounted on the board (U1 per Bill of Materials Table 4). It is supplied as a complete, ready-to-use evaluation PCB with all passive components installed, including two 100 pF 0402 DC-blocking capacitors and SMA connectors for RFIN, RFOUT, and VFCTL signals.

What RF layout techniques are implemented on the EV1HMC881ALP5?

The EV1HMC881ALP5 uses rigorous RF design practices: 50 Ω microstrip traces on Layer 1, three internal ground planes (L2/L3 solid copper), Rogers 4350 top dielectric for low loss, and mandatory multi-via grounding of the HMC881A's exposed pad and GND pins. These ensure minimal parasitic coupling and repeatable S-parameter measurements.

Can the EV1HMC881ALP5 be used for temperature-dependent characterization?

Yes - the EV1HMC881ALP5 supports full thermal validation of the HMC881A across its rated −40°C to +85°C operating range. Its robust grounding, low-thermal-resistance layout, and compatibility with environmental chambers allow measurement of key parameters like f_3dB drift (0.6 MHz/°C), insertion loss variation, and tuning sensitivity vs. temperature.

Is the EV1HMC881ALP5 RoHS compliant and JEDEC certified?

Yes, the EV1HMC881ALP5 is RoHS compliant and built to JEDEC MO-220-WHHD-5 standards for the underlying HMC881A LFCSP-32 package (CP-32-12). The PCB itself follows IPC Class 2 requirements, with documentation confirming compliance in Analog Devices' official ordering guide and datasheet Rev. 0.
