4-way PTT sequencer in BOX
This is simply 4-way PTT sequencer, designed for PTT switching from one input to 4 outputs with different (fixed) delay.
54.00 € (without tax)
This 4-way PTT sequencer is product designed for PTT switching from one input to 4 outputs with different (fixed) delay. You can split PTT signal to 4 independent devices with different timing: LNA, PA, RF relays etc. This device also protects your PTT output from external accessories. There is optocoupler isolator between PTT input and all four PTT outputs. Outputs are switched to ground when PTT is active. There are FET outputs without any additional delays.
Using
- PTT sequencer for LNA, PA, TRX etc.
- Power supply soft start
- CPU and peripheries reset
Main functions
- Universal (PTT) sequencer
- Protecting PTT input (TRX) from accessories - opto isolators
- FIXED delay 60 ms
- OUT T0 is without any delay with PTT IN
- 4x output FET switch - DC 50 V 0.5 A

Parameters
- Sequencer delay is fixed 60 ms
- Sequencer from RX to TX PTT IN to: T0 = 0 ms, T1 = 60 ms, T2 = 120 ms, T3 = 180 ms
- Sequencer from TX to RX PTT IN to: T0 = 0 ms, T1 = 180 ms, T2 = 120 ms, T3 = 60 ms
- Optocoupler isolator protection at PTT IN port
- OUTPUTS are open while input PTT is in RX, shorted to GND while input is in TX
- When you need to switch positive voltage (LNA) you can use P-FET switch - example
