Notes: 1. In a 2TX-1RX SP3T configuration, TX1 and TX2 are tied and TX3 and TX4 are tied respectively. Refer to Application Note AN35 for SP3T performance data
2. Narrow trace widths are used near each port to improve impedance matching. Refer to evaluation board layouts (Figure
23)
and schematic (Figure
24)
for details
3. 10% of 4620 µs period
4. Normal mode: connect Vss
EXT
(pin 16) to GND (Vss
EXT
= 0V) to enable internal negative voltage generator. Bypass mode: use Vss
EXT
(pin 16) to bypass and
disable internal negative voltage generator.
5. The input 0.1 dB compression point is a linearity figure of merit. Refer to
Table 3
for the RF input power P
