Analog Devices Inc. EVAL01-HMC996LP4E

Overview

EVAL01-HMC996LP4E from Analog Devices (formerly Hittite Microwave) is an evaluation board for the HMC996LP4E GaAs PHEMT MMIC variable gain amplifier, operating from 5–12 GHz. It provides full RF characterization capability with SMA connectors, DC bias headers, and optimized 50 Ω layout for measuring gain, IP3, P1dB, noise figure, and gain flatness across temperature and control voltage. Designed for microwave radio and radar subsystem validation.

For engineers reviewing the EVAL01-HMC996LP4E datasheet, EVAL01-HMC996LP4E pinout, EVAL01-HMC996LP4E application, or EVAL01-HMC996LP4E equivalent, this board enables rapid prototyping of X-band variable gain stages, EW/ECM front-end calibration, and high-frequency test equipment integration without custom PCB design.

Technical Context

The EVAL01-HMC996LP4E implements a fully populated, impedance-matched reference design for the HMC996LP4E amplifier IC, featuring RF input/output paths with AC-coupled 50 Ω SMA interfaces, dedicated DC bias headers (Vdd1/2, Vgg1/2, Vctrl), and decoupling networks using 100 pF (0402), 1000 pF (0603), and 2.2 µF (Case A) capacitors. The PCB uses Arlon 25FR substrate with controlled-impedance traces and multi-via grounding to the internal ground plane.

It supports full parametric evaluation under standard lab conditions: TA = +25°C, Vdd1/2 = +5 V, Vctrl = –1 to –4.5 V, and Idd = 120 mA typical. All measurements-including gain vs. frequency, IP3 vs. control voltage, and return loss over temperature-are traceable to the HMC996LP4E's published electrical specifications and absolute maximum ratings.

FAQ

What is the primary function of the EVAL01-HMC996LP4E evaluation board?

The EVAL01-HMC996LP4E evaluation board is a ready-to-use reference design that enables full RF characterization of the HMC996LP4E variable gain amplifier. It provides calibrated SMA interfaces, bias access headers, and optimized grounding to measure key parameters-including gain, IP3, P1dB, and noise figure-across 5–12 GHz without custom PCB development. The board directly supports lab validation of the HMC996LP4E in its intended operating conditions.

Does the EVAL01-HMC996LP4E require external power supplies or additional components to operate?

No external components are required beyond standard lab equipment. The EVAL01-HMC996LP4E includes all necessary decoupling (100 pF, 1000 pF, and 2.2 µF capacitors) and features DC bias headers (J5–J10) for direct connection to adjustable voltage sources. Users apply +5 V to Vdd1/2, –1 to –4.5 V to Vctrl, and –2 to 0 V to Vgg1/2 as specified in the HMC996LP4E datasheet. No additional matching or filtering is needed for basic operation.

What RF performance metrics can be measured using the EVAL01-HMC996LP4E?

Using the EVAL01-HMC996LP4E, engineers can measure the full suite of HMC996LP4E RF specifications: small-signal gain (13–18.5 dB), gain flatness (±0.5 dB typical), output P1dB (+22 dBm), saturated output power (+24 dBm), output IP3 (+34 dBm), noise figure (2 dB), and input/output return loss (9–23 dB). All data aligns with the published electrical specs at TA = +25°C and supports temperature sweep validation via environmental chamber mounting.

Is the EVAL01-HMC996LP4E compatible with automated test equipment (ATE) and vector network analyzers?

Yes - the EVAL01-HMC996LP4E is fully compatible with VNA, spectrum analyzer, and ATE setups. Its SMA-connected RF ports (J1 input, J4 output) meet industry-standard 50 Ω impedance and mechanical interface requirements. The board's low-loss Arlon 25FR substrate, controlled trace geometry, and multi-via grounding ensure measurement repeatability and minimal parasitic coupling, enabling accurate S-parameter and distortion measurements up to 12 GHz.

Where can I obtain the layout files or land pattern recommendations for the HMC996LP4E IC used on the EVAL01-HMC996LP4E?

Official land pattern recommendations and assembly guidelines for the HMC996LP4E IC are provided in Hittite Application Note "MMIC Amplifier Biasing Procedure" and the HMC996LP4E package drawing. While the EVAL01-HMC996LP4E PCB layout is proprietary, Analog Devices publishes recommended pad dimensions, via placement, and grounding rules for the 24-lead 4×4 mm QFN package - including mandatory soldering of all ground leads and the exposed paddle to the PCB ground plane.
