Here's a summary of the provided datasheet for the M/A-COM SW-489 GaAs SP3T switch:

Overview:

️· The SW-489 is a single-pole, three-throw (SP3T) high-power switch designed for applications like GSM/DCS handset systems.
️· It's fabricated using 0.5-micron GaAs pHEMT technology.
️· The switch is housed in a compact 12-lead FQFP package (3x3mm).

Key Features:

️· Low Voltage Operation: Operates at a low control voltage (2.5V).
️· Low Harmonics: Offers good harmonic performance (>65 dBc at +34 dBm and 1 GHz).
️· Low Insertion Loss: 0.5 dB at 1 GHz.
️· High Isolation: 18.5 dB at 2 GHz.
️· Small Size: Compact FQFP package.

Specifications:

️· Frequency Range: Up to 2.5 GHz.
️· Control Voltages: V1, V2, V3 control the switch's throw configuration (see truth table in datasheet).

️· Insertion Loss: 0.5 dB at 1 GHz
️· Isolation: 18.5 dB at 2 GHz
️· P1dB: 38 dBm
️· Harmonic Performance: >65 dBc
