UPG2031TQ-A

RF Switches Overview

The UPG2031TQ-A is a Gallium Arsenide (GaAs) Single Pole Triple Throw (SP3T) RF switch IC manufactured by CEL. Designed for L-band applications, it operates within a frequency range of 500 MHz to 2000 MHz. The device features a typical insertion loss of 0.8 dB and offers high off-isolation, typically measuring 17 dB. It supports a control voltage range of 2.7 V to 3 V and functions reliably across an operating temperature spectrum from -45°C to +85°C. The component is housed in a compact TSON-10 surface-mount package, facilitating integration into space-constrained wireless communication systems.

RF Switches Procurement Notes

Verify the specific suffix designation when ordering, as variations such as E1 may indicate distinct packaging or tape-and-reel specifications compared to the base model. Confirm that the supplier provides official datasheets matching the exact part number to ensure compatibility with design-in requirements. Cross-reference the manufacturer's current documentation to validate RoHS compliance status and recommended soldering profiles for the TSON-10 package.

RF Switches Selection Notes

Select this component for designs requiring compact SP3T switching solutions in the L-band frequency spectrum. Ensure the application environment remains within the specified -45°C to +85°C operational limits. Verify that the system power supply can maintain the required 2.7 V to 3 V control voltage range without fluctuation. Consider the TSON-10 footprint constraints during PCB layout to ensure adequate thermal dissipation and signal integrity for high-frequency operations up to 2 GHz.
