AS115-61
Description
The AS115-61 is a high isolation SP4T FET IC non-
reflective switch. The switch operates with 0 and -3 V or
-5 V over the frequency range of DC2 GHz. The insertion
loss is 0.7 dB and isolation is 50 dB at 0.9 GHz. The switch
is ideal for cellular base station switch matrices.
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. Input/output.
5. Video feedthru measured with 1 ns risetime pulse and 500 MHz bandwidth.
