ASC02D2-12
(Previously ADC02D2-12)*
Description
The ASC02D2-12 is a 4 port switch with independent
DC voltage control on each port mounted in the
SOIC-8 package. In transmit or receive applications, the
asymmetric design allows for good isolation between
transmit and receive path while maintaining medium power
handling in transmit port.

Operating Characteristics at 25C (0, -5 V)
1. All measurements made in a 50
system, unless otherwise specified.
2. DC = 300 kHz.
3. Insertion loss changes by 0.003 dB/C.
4. Insertion loss state.
5. Video feedthru measured with 1 ns risetime pulse and 500 MHz bandwidth.
*Due to conflict with another company's product numbering system, Alpha's attenuator product "ADC02D2-12" is being changed to "ASC02D2-12".
