1) Insertion loss and isolation performance can be improved by a good RF ground on the LS pin (pin 1).
2) Defined with S-parameters, relative insertion phase (RFX–RF1) = ∠S
– ∠S , where incident Port-1 is RFC, response Port-2 = RF1, and

(x+1)1
response Port-(x+1) = RFx.
3) The input 1dB and 0.1dB compression point are linearity figures of merit. Refer to Table 2 for the RF input power (50Ω).
Switching Frequency
Thermal Data
Psi-JT (ΨJT), junction top-of-package, is a thermal
metric to estimate junction temperature of a device on
the customer application PCB (JEDEC JESD51-2).
The PE426482 has a maximum 25 kHz switching
frequency. Switching frequency describes the time
duration between switching events. Switching time is
the time duration between the point the control signal
reached 50% of the final value and the point the
output signal reaches within 10% or 90% of its target
value.
ΨJT = (TJ – TT)/P
where
ΨJT = junction-to-top of package characterization
parameter, °C/W
Spurious Performance
The PE426482 spur fundamental occurs around
5 MHz. Its typical performance is –162 dBm/Hz, with
30 kHz bandwidth.
TJ = die junction temperature, °C
TT = package temperature (top surface, in the
center), °C
P = power dissipated by device, Watts
Hot-Switching Capability
The maximum hot switching capability of the
PE426482 is 18 dBm above 100 MHz. Hot switching
occurs when RF power is applied while switching
between RF ports.
