Christian Mayer
High Reliable Electronic Components for Space, Avionic, Military, HighVoltage, HighTemperature, Medical, and other demanding Applications.
The ISL71934M is a high reliability, low insertion loss, 50Ω SP2T absorptive RF switch designed for a multitude of wireless and other RF applications. This device covers a broad frequency range from 50MHz to 6000MHz. In addition to providing low insertion loss, the ISL71934M delivers high linearity and high isolation performance while providing a 50Ω termination to the unused RF input port.
The ISL71934M uses a single positive supply voltage of 2.7V to 5.25V supporting three states using either 3.3V or 1.8V control logic.
Characterized radiation levels: Low Dose Rate (LDR) (0.01rad(Si)/s): 30krad(Si), Single event burnout LET 43MeV?cm2/mg
Applications: Satellite communications system, Antenna switching, IF switching, Digital pre-distortion feedback
Competitive Advantage: The ISL71934M provides the following advantages:
- Constant impedance K|Z| during switching transition
- Insertion loss = 0.79dB (at 2GHz)
- RFX to RFC isolation = 67dB (at 2GHz)
- IIP3 = +64dBm (at 2GHz)
- Active port operating power handling = 34dBm
- Term port operating power handling = 27dBm
