The ADRF5020 is a general-purpose, single-pole, double-throw (SPDT) switch manufactured using a silicon process. It comes in a 3 mm × 3 mm, 20-terminal land grid array (LGA) package and provides high isolation and low insertion loss from 100 MHz to 30 GHz.
This broadband switch requires dual supply voltages, +3.3 V and −2.5 V, and provides CMOS/LVTTL logic-compatible control.
The ADRF5020 requires a positive supply voltage applied to the VDD pin and a negative supply voltage applied to the VSS pin. Bypassing capacitors are recommended on the supply lines to minimize RF coupling.
The ADRF5020 is internally matched to 50 Ω at the RF common port (RFC) and the RF throw ports (RF1 and RF2); therefore, no external matching components are required. All of the RF ports are dc-coupled to 0 V, and no dc blocking is required at the RF ports when the RF line potential is equal to 0 V. The design is bidirectional; the RF input signal can be applied to the RFC port while the RF throw port (RF1 or RF2) is output or vice versa.
The ADRF5020 incorporates a driver to perform logic functions internally and to provide the user with the advantage of a simplified control interface. The driver features two digital control input pins, CTRL and EN.
