SA630
Single-Pole Double-Throw (SPDT) switch
Rev. 3 — 23 July 2014
Product data sheet
1. General description
The SA630 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
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 SA630 ideal for portable applications.
The excellent isolation and low loss makes this device a suitable replacement for PIN
diodes.
The SA630 is available in an 8-pin SO (surface-mounted miniature) package.
2. Features and benefits
Wideband (DC to 1 GHz)
Low through loss (1 dB typical at 200 MHz)
Unused input is terminated internally in 50
Excellent overload capability (1 dB gain compression point +18 dBm at 300 MHz)
Low DC power (170
A
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
match (return loss 18 dB at 400 MHz)
Full ESD protection
Bidirectional operation
3. Applications
Digital transceiver front-end switch
Antenna switch
Filter selection
Video switch
FSK transmitter
