Analog Devices Inc. ADTR1107-EVAL

Overview

ADTR1107-EVALZ from Analog Devices is a 2-layer Rogers 4350B evaluation board designed specifically for the ADTR1107 6 GHz to 18 GHz front-end IC, featuring an integrated aluminum heat sink, four 2.9 mm female RF connectors (TX_IN, ANT, RX_OUT, CPLR_OUT), and dual 24-pin control headers for bias and logic access.

For engineers reviewing the ADTR1107-EVALZ datasheet, ADTR1107-EVALZ pinout, ADTR1107-EVALZ application, or ADTR1107-EVALZ equivalent, this board enables RF characterization of the ADTR1107's transmit/receive switching, gain, noise figure, and linearity across its full 6–18 GHz bandwidth under controlled thermal and bias conditions.

Technical Context

The ADTR1107-EVALZ provides calibrated RF paths with 50 Ω grounded coplanar waveguide traces and supports full bias sequencing for both TX and RX operational states. It implements discrete DC bias delivery via J5 and J6 headers for VDD_PA (5 V), VGG_PA (0 V to −2 V), VDD_LNA (3.3 V), VGG_LNA (0 V to −1.5 V), and dual ±3.3 V for the switch core.

A through-calibration path (J7–J8, unpopulated) is included with measured insertion loss from −0.5 dB at 6 GHz to −1.4 dB at 18 GHz. The board operates over −40°C to +85°C and uses component-level thermal management via direct paddle-to-ground vias and mechanical coupling to the aluminum heat sink.

FAQ

What is the primary function of the ADTR1107-EVALZ?

The ADTR1107-EVALZ is a dedicated evaluation board for the ADTR1107 6–18 GHz transmit/receive front-end IC. It provides calibrated RF interfaces, thermal management, and full bias control to enable lab-based measurement of gain, noise figure, P1dB, and harmonic performance without custom PCB development.

Which RF connectors are used on the ADTR1107-EVALZ?

The ADTR1107-EVALZ uses four 2.9 mm female coaxial connectors - labeled TX_IN, ANT, RX_OUT, and CPLR_OUT - sourced from Winchester Connector (P/N 25-146-1000-92). These support broadband operation up to 40 GHz with low insertion loss and consistent 50 Ω impedance match.

Does the ADTR1107-EVALZ include a populated through-calibration path?

No, the through-calibration path (J7 to J8) on the ADTR1107-EVALZ is unpopulated per the Bill of Materials and User Guide. Users must install appropriate 2.9 mm connectors and perform calibration to use this path for trace loss de-embedding.

What power supplies are required to operate the ADTR1107-EVALZ?

Five independent supplies are required: 5 V/1 A (VDD_PA), 3.3 V/100 mA (VDD_LNA), 0 V to −2 V/100 mA (VGG_PA), and dual ±3.3 V/100 mA (VDD_SW/VSS_SW). All connect via designated pins on J5 and J6 headers following documented bias sequencing.

How is thermal management implemented on the ADTR1107-EVALZ?

The ADTR1107-EVALZ mounts the ADTR1107 directly onto a 2.51″ × 1.9″ aluminum heat sink using thermal interface material. Multiple vias beneath the exposed paddle ensure low-impedance conduction to the ground plane, while mounting holes allow attachment to larger external heatsinks for sustained high-power operation.
