General description
The SA58643 is a wideband RF switch fabricated in BiCMOS technology and incorporating on-chip CMOS/TTL compatible drivers. Its primary function is to switch signals in the frequency range DC to 1 GHz from one 50 Ohm channel to another. The switch is activated by a CMOS/TTL compatible signal applied to the enable channel 1 pin (ENCH1).
The extremely low current consumption makes the SA58643 ideal for portable applications. The excellent isolation and low loss makes this a suitable replacement for PIN diodes.
The SA58643 is available in an 8-pin TSSOP package.
Features
- Wideband (DC to 1 GHz)
- Low through loss (1 dB typical at 200 MHz)
- Unused input is terminated internally in 50 Ohm
- Excellent overload capability (1 dB gain compression point +18 dBm at 300 MHz)
- Low DC power (170 uA from 5 V supply)
- Fast switching (20 ns typical)
- Good isolation (off channel isolation 60 dB at 100 MHz)
- Low distortion (IP3 intercept +33 dBm)
- Good 50 Ohm match (return loss 18 dB at 400 MHz)
- Full ESD protection
- Bidirectional operation
