Analog Devices Inc. EVAL01-HMC935LP5E

Overview

EVAL01-HMC935LP5E from Analog Devices (formerly Hittite Microwave) is an evaluation PCB designed to characterize the HMC935LP5E 180° analog phase shifter across 2–20 GHz, supporting RF input/output via 2.9 mm connectors and DC control voltage interface. It enables precise measurement of phase shift linearity, insertion loss variation, and return loss under varying V_ctl (0.5–11 V) and temperature (−40°C to +85°C).

For engineers reviewing the EVAL01-HMC935LP5E datasheet, EVAL01-HMC935LP5E pinout, EVAL01-HMC935LP5E application, or EVAL01-HMC935LP5E equivalent, this board provides validated RF layout practices-including 50 Ω microstrip routing, ground-via density guidance, and thermal management via exposed paddle soldering-to accelerate prototyping of EW receivers, radar beamforming modules, and satellite communication front-ends.

Technical Context

The EVAL01-HMC935LP5E implements a controlled RF test environment for the HMC935LP5E phase shifter, featuring two 2.9 mm female RF connectors (J1, J2) with 40 GHz bandwidth, DC solder pins (J4, J5) for V_ctl and ground, and a Rogers 4350 or Arlon 25 FR substrate optimized for stable high-frequency impedance matching.

Its layout enforces critical RF design rules: direct connection of the HMC935LP5E's exposed ground paddle to the PCB ground plane via multiple thermal vias, strict 50 Ω trace geometry, and minimized stub lengths-ensuring accurate characterization of phase error (±20/−8° typ.), insertion loss (4 dB typ.), and modulation bandwidth (10 MHz).

FAQ

What is the primary purpose of the EVAL01-HMC935LP5E evaluation board?

The EVAL01-HMC935LP5E evaluation board is a dedicated test platform for characterizing the HMC935LP5E 180° analog phase shifter across its full 2–20 GHz operating band. It provides calibrated RF paths, stable DC biasing, and thermally robust mounting to measure phase linearity, insertion loss, return loss, and harmonic distortion under real-world conditions-enabling rapid validation before integration into EW, radar, or satcom systems.

Does EVAL01-HMC935LP5E include the HMC935LP5E IC, or is it sold separately?

EVAL01-HMC935LP5E includes the HMC935LP5E analog phase shifter (U1) pre-mounted on the PCB, along with 2.9 mm RF connectors (J1, J2), DC solder pins (J4, J5), and a Rogers 4350 or Arlon 25 FR substrate. No additional ordering of the HMC935LP5E IC is required-the evaluation board ships as a complete, ready-to-test assembly.

What RF connector type is used on EVAL01-HMC935LP5E, and what is its frequency limit?

EVAL01-HMC935LP5E uses 2.9 mm female coaxial connectors (J1 and J2) rated for DC to 40 GHz. This exceeds the 2–20 GHz operational range of the HMC935LP5E, ensuring minimal connector-induced loss or phase distortion during full-band characterization and enabling margin for future higher-frequency testing.

How is thermal performance managed on the EVAL01-HMC935LP5E board?

EVAL01-HMC935LP5E manages thermal performance by directly soldering the HMC935LP5E's exposed ground paddle to the PCB ground plane using ≥8 thermal vias, and specifying mechanical mounting to an external heat sink. This configuration maintains junction temperature ≤87 °C at 10 dBm input power-matching the HMC935LP5E's nominal thermal operating point and supporting reliable long-term evaluation.

Can EVAL01-HMC935LP5E be used to evaluate phase error versus temperature?

Yes, EVAL01-HMC935LP5E supports phase error versus temperature evaluation across −40°C to +85°C. Its layout preserves the HMC935LP5E's thermal path integrity, and the board's RF and DC interfaces remain stable across temperature extremes-enabling measurement of the device's specified ±0.07 deg/°C insertion phase temperature sensitivity and peak phase error of +28/−15° over full band and control voltage range.
