Notes:
1. T
C
is defined as case temperature, the temperature of the underside of the
duplexer where it makes contact with the circuit board. Port 1 = Tx,
Port 2 = Rx, Port 3 = Ant
2. Specifications are given at operating temperature limits and room
temperature. To estimate performance at some intermediate temperature,
use linear interpolation.
3. Specifications are guaranteed over the given temperature range, with the
input power to the Tx port equal to +29 dBm (or lower) over all Tx
frequencies. Upper transmit band edge maximum Insertion Loss at 85°C
is guaranteed to +26 dBm of input power. For higher input power, derate
maximum temperature as: Tmax = 95°C – 25°C * Pin (Watts). Input power
between +26 dBm and +30 dBm is safe, but the Insertion Loss at the
upper transmit band edge will degrade slightly.
4. High temperature specifications are guaranteed with thermal pads in
thermal contact with the motherboard. (See Figure 1.)
Thermal Pads ensure good
thermal contact to the motherboard.
