Description
The AK115-61 is a high isolation SP4T FET IC non-
reflective switch with integral driver. 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 (+5, -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.
6. Supply voltage and ground must be connected before control voltage is
applied to avoid irreversible damage to the device.
7. Current increases from 16 mA to 20 mA @ +85C.
