　　The ADTR1107 is a compact, 6 GHz to 18 GHz, front-end IC with an integrated power amplifier, low noise amplifier (LNA), and a reflective single-pole double-throw (SPDT) switch. These integrated features make the device ideal for phased array antenna and radar applications. The front-end IC offers 25 dBm of saturated output power (PSAT) and 22 dB small signal gain in transmit state, and 18 dB small signal gain and 2.5 dB noise figure in receive state. The device has a directional coupler for power detection. The input/outputs (I/Os) are internally matched to 50 Ω. The ADTR1107 is supplied in a 5 mm × 5 mm, 24-terminal, land grid array (LGA) package.

　　The ADTR1107-EVAL evaluation board consists of a two-layer printed circuit board (PCB) fabricated from a 10 mil thick, Rogers 4350B copper clad mounted to an aluminum heat sink. The heat sink assists in providing thermal relief to the device as well as mechanical support to the PCB. Mounting holes on the heat sink allow attachment to larger heat sinks for improved thermal management.

　　The TX_IN, ANT, RX_OUT, and CPLR_OUT ports are populated by 2.9 mm, female coaxial connectors. The respective RF traces of the ports have a 50 Ω characteristic impedance. The ADTR1107-EVAL is populated with components suitable for use over the −0°C to +85°C operating temperature range of the ADTR1107. To calibrate board trace losses, a through calibration path is provided. However, to use the through calibration path, users must install and populate the path with RF connectors.

　　Access to drain, ground, and gate control voltages is through two, 24-pin headers.

　　RF traces are 50 Ω grounded, coplanar waveguide. Package ground leads and the exposed paddle connect directly to the ground plane. Multiple vias connect the top and bottom ground planes with particular focus on the area directly beneath the ground paddle to provide adequate electrical conduction and thermal conduction to the heat sink.
