Nonreflective RF Path Selector SP3T with Bypass, 100MHz to 20GHz

The ADRF5060 is a bidirectional, nonreflective RF path selector, SP3T with bypass manufactured in a silicon on insulator (SOI) process.

The ADRF5060 operates from 100MHz to 20GHz with an insertion loss of lower than 1.3dB on through path and isolation of higher than 42dB. The ADRF5060 has an RF input power handling capability of 33dBm external paths, 18dBm terminated path, and 30dBm hot switching at the RFIN or RFOUT port.

The ADRF5060 requires a dual-supply voltage of +3.3V and −3.3V. The device can also operate with a single positive supply voltage (VDD) pin applied while the negative supply pin (VSS) is tied to ground. In this operating condition, the small signal performance is maintained while the switching characteristics, linearity, and power handling performance are derated, see Figure 2 in data sheet.

The ADRF5060 employs complimentary metal-oxide semiconductor (CMOS)-/low-voltage, transistor to transistor logic (LVTTL) logic-compatible controls.

The ADRF5060 has three digital input pins (V1, V2, and XC) to control the digital switch states, including an all-off state and an additional control for cross port selection. See the Theory of Operation section for additional information.

The ADRF5060 comes in a 4 mm × 3 mm, LGA package.
