Which model is the TTL-controlled RF switch, and what topology does it use?
It is the QT-06SPD2W: one RF input and two RF outputs, with RF01 and RF02 as the two selectable paths. It covers 0.1–8 GHz at 50 Ω with SMA female connectors, insertion loss under 1 dB and isolation above 70 dB from 0.1–3 GHz, controlled over DC 5 V Type-C with AT commands. Multi-path matrix configurations are a separate model and have to be confirmed rather than assumed from this part number.
Key points
- QT-06SPD2W is 1 input to 2 outputs, not a matrix
- 0.1–8 GHz, 50 Ω, SMA female
- Insertion loss under 1 dB and isolation above 70 dB from 0.1–3 GHz
- Above 3 GHz: under 3 dB insertion loss and above 50 dB isolation
- AT+RF0 and AT+RF1 select the path and return OK
