Analog Devices Inc. EVAL01-HMC1055LP2C

Overview

EVAL01-HMC1055LP2C from Analog Devices is an evaluation board for the HMC1055 GaAs SPST RF switch, supporting 0.5–4.0 GHz operation with 0.7 dB typical insertion loss at 2.0 GHz, >60 dBm IP3, and single 3 V control logic. It enables rapid characterization of RF switching performance in cellular infrastructure and test equipment signal paths.

For engineers reviewing the EVAL01-HMC1055LP2C datasheet, EVAL01-HMC1055LP2C pinout, EVAL01-HMC1055LP2C application, or EVAL01-HMC1055LP2C equivalent, this page delivers verified layout guidance, calibrated PCB trace impedance (50 Ω CPWG), SMA interface details, thermal via placement, and dc biasing schematics per Analog Devices' official evaluation design.

Technical Context

The EVAL01-HMC1055LP2C implements a 4-layer FR-4/RO4350 hybrid PCB with top-layer coplanar waveguide (CPWG) transmission lines-16 mil width, 13 mil spacing, 10 mil dielectric-to maintain 50 Ω characteristic impedance across 0.5–4.0 GHz. RF ports J1 (RF1) and J2 (RF2) are ac-coupled via 330 pF 0402 capacitors; dc bias is applied through J3 (VDD) and J4 (VCTL).

Thermal management uses dense via arrays under the HMC1055's exposed pad and ground pins (pins 2, 3), connected to inner and bottom ground planes. A 1 nF decoupling capacitor (C1) filters VDD noise, and a thru-calibration line (J5–J6) enables on-board loss de-embedding during VNA measurements.

FAQ

What is the primary function of the EVAL01-HMC1055LP2C evaluation board?

The EVAL01-HMC1055LP2C evaluation board is a dedicated test platform for the HMC1055 GaAs SPST RF switch. It provides fully routed 50 Ω CPWG transmission lines, SMA connectors (J1/J2), dc bias interfaces (J3/J4), and thermal vias to enable accurate S-parameter measurement, linearity testing (IP3, P0.1dB), and thermal validation of the HMC1055 under real-world RF operating conditions.

Does the EVAL01-HMC1055LP2C include the HMC1055 IC, and what package does it support?

Yes, the EVAL01-HMC1055LP2C includes one HMC1055 IC mounted in its native 8-lead, 2 mm × 2 mm LFCSP package (CP-8-26). The board's footprint, solder mask, and thermal via pattern are precisely aligned to the HMC1055LP2CE/LP2CETR package outline and exposed pad requirements specified in Analog Devices' datasheet Rev. B.

How is RF calibration supported on the EVAL01-HMC1055LP2C?

The EVAL01-HMC1055LP2C includes a dedicated thru calibration line connecting SMA connectors J5 and J6. This 50 Ω reference path allows vector network analyzers to perform SOLT or TRL calibration directly on the board, enabling precise de-embedding of PCB trace loss and fixture effects when measuring the HMC1055's true RF performance.

What dc decoupling and filtering components are populated on the EVAL01-HMC1055LP2C?

The EVAL01-HMC1055LP2C populates a 1 nF 0402 capacitor (C1) on the VDD supply line (J3) for high-frequency noise suppression. No additional bulk capacitance is required due to the low quiescent current (0.2 mA) of the HMC1055. The VCTL line (J4) has no series resistor or capacitor, as the HMC1055 draws <5 µA control current.

Can the EVAL01-HMC1055LP2C be used for thermal performance evaluation?

Yes-the EVAL01-HMC1055LP2C supports thermal evaluation via its dense array of thermal vias under the HMC1055's exposed pad and ground pins (2, 3), all connected to inner and bottom ground planes. This design replicates the thermal resistance (θJC = 74°C/W) specified in the HMC1055 datasheet, allowing junction temperature estimation during high-power RF operation.
