A high-power-handling GSM switch IC with new adaptive-control-voltage-generator circuit scheme

We propose a high-power-handling switch circuit using a new adaptive-control-voltage-generator circuit (AVG). This AVG enables the internal control node voltages to be automatically increased in high-input-power conditions. This switch circuit results in high-power-handling, low-insertion-loss, small chip size and low voltage control. The developed IC demonstrated a handling power of 36.5 dBm and an insertion loss of 0.31 dB with 40% chip size reduction.
