Featuring dual-channel 2.4GHz radios, the RP4TD excels in signal sensitivity, signal-to-noise ratio, and overall performance due to its optimized circuit design. The reliable DCDC power supply circuit ensures lower operating temperatures during extended usage. Additionally, the dual TCXO contributes to the utmost frequency stability and makes the RP4TD a leader in its class. The RP4TD features built in WIFI so you can wirelessly upgrade firmware to configure the receiver via the built-in WebUI with your PC or mobile phone.

Suitable for almost any application, the receiver can be installed wherever a compact, high-performance serial link is required!

Dual TCXO (temperature compensated crystal oscillator)

The TCXO ensures high stability and accuracy in frequency control, compensating for temperature variations. This results in consistent and reliable signal reception, even in extreme temperature conditions. It also reduces frequency drift over time, providing long-term frequency stability and preventing signal degradation. In our testing, we found that two TCXOs offer better advantages in true diversity receivers.
