TC is the case temperature and is defined as the temperature of the underside of the duplexer where it makes contact with the circuit board. 2. Specifications guaranteed over the given temperature range (unless otherwise noted) with the input power to the Tx port equal to or less than +29 dBm over all Tx frequencies. 3. Typical data is the arithmetic mean value of the parameter over its indicated frequency range at the specified temperature. Typical values may vary from part to part and over time.
