Analog Devices Inc. ADTR1107-EVALZ

Overview

ADTR1107-EVALZ from Analog Devices is an evaluation board for the ADTR1107 6 GHz to 18 GHz front-end IC, integrating a power amplifier, low-noise amplifier, and reflective SPDT switch in a single 5 mm × 5 mm LGA package. It enables rapid characterization of transmit/receive switching, 25 dBm PSAT, 2.5 dB receive noise figure, and directional coupler–based power monitoring in phased array radar systems.

For engineers reviewing the ADTR1107-EVALZ datasheet, ADTR1107-EVALZ setup guide, ADTR1107-EVALZ RF performance validation, or ADTR1107-EVALZ compatibility with ADAR1000 beamformers, this board provides calibrated 50 Ω RF interfaces, bias sequencing control, thermal management provisions, and documented layout practices for Ka-band T/R module development.

Technical Context

The ADTR1107-EVALZ implements full RF signal path validation for the ADTR1107 IC across its 6–18 GHz operating range, supporting both transmit (TX_IN → ANT) and receive (ANT → RX_OUT) states via a single CTRL_SW logic line. It replicates production-level bias conditions: VDD_PA = 5 V, VDD_LNA = 3.3 V, VDD_SW = 3.3 V / VSS_SW = −3.3 V, and includes on-board decoupling, thermal vias, and impedance-matched microstrip routing.

Designed per JEDEC 2S2P thermal test board standards, the evaluation board features 36 thermal vias under the ADTR1107's exposed pad to achieve θJC = 52.7°C/W (transmit) and 198.4°C/W (receive), enabling stable operation at 1.71 W max dissipation. All RF ports-TX_IN, ANT, RX_OUT, and CPLR_OUT-are dc-coupled, 50 Ω matched, and connectorized with SMA edge-mount interfaces.

FAQ

What is the primary function of the ADTR1107-EVALZ?

The ADTR1107-EVALZ is an evaluation board designed exclusively to characterize and validate the ADTR1107 front-end IC. It provides full RF access, calibrated bias networks, thermal management, and documented layout practices to support engineering verification of 6–18 GHz transmit/receive switching, gain, noise figure, and power detection performance in radar and phased array systems. The ADTR1107-EVALZ does not contain active circuitry beyond what is needed to operate the ADTR1107 IC.

Does the ADTR1107-EVALZ support both transmit and receive state testing?

Yes, the ADTR1107-EVALZ fully supports dual-state operation of the ADTR1107 IC. It enables seamless transition between transmit (TX_IN → ANT) and receive (ANT → RX_OUT) modes using the single CTRL_SW digital control line, with verified bias sequencing for VDD_PA, VDD_LNA, VDD_SW, and VSS_SW. Measured RF settling time is ≤22 ns to 0.05 dB final value, matching ADTR1107 specification limits.

Can the ADTR1107-EVALZ be used with the ADAR1000 beamformer?

Yes, the ADTR1107-EVALZ is explicitly validated for interfacing with the ADAR1000 X-band and Ku-band beamformer, as documented in Analog Devices' "Interfacing the ADTR1107 to the ADAR1000" application note (page 26 of Rev. C datasheet). The board maintains 50 Ω impedance continuity and timing alignment required for coherent beamforming in multi-channel AESA systems.

What RF connectors are used on the ADTR1107-EVALZ?

The ADTR1107-EVALZ uses edge-mount SMA connectors for all four RF ports: TX_IN, ANT, RX_OUT, and CPLR_OUT. Each connector is dc-coupled and impedance-matched to 50 Ω, enabling direct connection to vector network analyzers, signal generators, and spectrum analyzers without external bias tees or dc blocks.

Is thermal management implemented on the ADTR1107-EVALZ?

Yes, the ADTR1107-EVALZ implements JEDEC 2S2P-compliant thermal design with 36 thermal vias beneath the ADTR1107's exposed pad, ensuring θJC = 52.7°C/W in transmit mode and enabling safe operation at the IC's maximum 1.71 W power dissipation. This layout directly supports reliability validation under sustained RF output conditions.
