Additional Details

The AS177-86LF is typically supplied in a compact SOT-26 package. It requires a positive DC supply voltage for operation. Key specifications include low insertion loss (typically less than 0.5 dB at 2.4 GHz), high isolation (typically greater than 25 dB at 2.4 GHz), and high linearity (typically greater than +50 dBm IP3). The switch is designed for broadband operation across a wide range of frequencies. The datasheet should be consulted for precise specifications regarding operating frequency, voltage, current, and temperature ranges.
