UPG2155TB-A

RF Switches Overview

The UPG2155TB-A is a single-pole double-throw (SPDT) RF switch IC manufactured by CEL. It operates within a frequency range of 500 MHz to 2.5 GHz, with specific testing conducted at 2.5 GHz. The device features an isolation of 17 dB and an insertion loss of 0.45 dB at the test frequency. It maintains a standard impedance of 50 Ohms. The component is housed in a 6-SuperMiniMold package, equivalent to 6-TSSOP or SC-88/SOT-363. It supports an operating temperature range from -45°C to 85°C.
