Single pole double throw (SPDT) switch

The isolation and matching of the two channels over frequency is
shown in Figures 15 and 17, respectively.
The SA630 is a very versatile part and can be used in many
applications. Figure 5 shows a block diagram of a typical Digital RF
transceiver front-end. In this application the SA630 replaces the
duplexer which is typically very bulky and lossy. Due to the low
power consumption of the device, it is ideally suited for handheld
applications such as in CT2 cordless telephones. The SA630 can
also be used to generate Amplitude Shift Keying (ASK) or On-Off
Keying (OOK) and Frequency Shift Keying (FSK) signals for digital
RF communications systems. Block diagrams for these applications
are shown in Figures 6 and 7, respectively.
For applications that require a higher isolation at 1GHz than
obtained from a single SA630, several SA630s can be cascaded as
shown in Figure 8. The cascaded configuration will have a higher
loss but greater than 35dB of isolation at 1GHz and greater than
65dB @ 500MHz can be obtained from this configuration. By
modifying the enable control, an RF multiplexer/ de-multiplexer or
antenna selector can be constructed. The simplicity of SA630
coupled with its ease of use and high performance lends itself to
many innovative applications.
The SA630 switch terminates the OFF channel in 50
. The 50
resistor is internal and is in series with the external AC bypass
capacitor. Matching to impedances other than 50
can be achieved
by adding a resistor in series with the AC bypass capacitor (e.g.,
25
additional to match to a 75
environment).
