Qorvo 880148 EVAL BOARD

Overview

880148 EVAL BOARD from Aetrix Electronics is a high-frequency RF evaluation platform designed for characterizing S-parameter performance of passive and active components in the 2.12–2.89 GHz band. It supports calibrated vector network analyzer (VNA) measurements with 50 Ω impedance, provides traceable reference planes at SMA connectors, and enables validation of insertion loss, return loss, and group delay in microwave front-end designs.

For engineers reviewing the 880148 EVAL BOARD datasheet, pinout, applications, or equivalent options, this board delivers factory-trimmed measurement repeatability, documented reference plane offsets, and compatibility with Keysight/Anritsu/Rohde & Schwarz VNAs - critical for RF filter, duplexer, and PA module development requiring sub-0.1 dB amplitude accuracy and ±0.5° phase stability.

Technical Context

The 880148 EVAL BOARD implements a symmetric two-port transmission line structure with edge-mounted SMA-F connectors, precision-machined 50 Ω microstrip routing, and ground-signal-ground (GSG) coplanar launch geometry. Its layout minimizes discontinuity-induced ripple below –40 dB across the validated 2.12–2.89 GHz band.

Calibration data (S11, S21, S12, S22) is provided per frequency point from 2124.0 to 2288.5 MHz in 0.5 MHz steps, enabling de-embedding of fixture effects using standard VNA error models (SOLT, TRL). Measured dynamic range exceeds 100 dB at 2.45 GHz.

FAQ

What is the primary purpose of the 880148 EVAL BOARD?

The 880148 EVAL BOARD serves as a calibrated two-port reference fixture for vector network analyzer measurements. It enables accurate de-embedding of test fixture effects when characterizing RF components such as filters, baluns, and matching networks between 2124.0 and 2288.5 MHz. The 880148 EVAL BOARD includes full S-parameter datasets for error model generation and supports industry-standard SOLT calibration.

Does the 880148 EVAL BOARD require external calibration standards?

No - the 880148 EVAL BOARD is supplied with a complete, frequency-resolved S-parameter dataset (S11, S21, S12, S22) covering 2124.0–2288.5 MHz in 0.5 MHz increments. This dataset allows direct implementation of custom error models in Keysight PathWave, Copper Mountain, or Python-based VNA software without additional mechanical standards. The 880148 EVAL BOARD reference planes are physically defined at the SMA connector mating interfaces.

Can the 880148 EVAL BOARD be used beyond 2.89 GHz?

While the 880148 EVAL BOARD's physical construction supports operation up to 18 GHz, its published calibration data and verified performance metrics (e.g., insertion loss flatness, return loss ≥15 dB) are strictly limited to 2124.0–2288.5 MHz. Use above 2.89 GHz requires user validation; no S-parameter data or uncertainty specifications are provided by Aetrix Electronics for frequencies outside this band for the 880148 EVAL BOARD.

What substrate material is used in the 880148 EVAL BOARD?

The 880148 EVAL BOARD uses Rogers RO4350B laminate (0.508 mm thickness) with a dielectric constant of 3.66 ±0.05 at 10 GHz and low moisture absorption (<0.02%). This material ensures stable phase response and minimal dispersion across the 2.12–2.89 GHz operating band, directly supporting the 880148 EVAL BOARD's specified ±0.5° phase repeatability.

Is the 880148 EVAL BOARD compatible with non-Aetrix RF components?

Yes - the 880148 EVAL BOARD is a universal two-port test fixture with standard 50 Ω SMA-F interfaces and no active circuitry. It is routinely used to characterize third-party filters, duplexers, LNAs, and PAs. Its documented reference planes and supplied S-parameter file allow seamless integration into any VNA workflow, regardless of component manufacturer - including full support for de-embedding the 880148 EVAL BOARD's own response from DUT measurements.
