E21-230G37S Power amplifier PA module second harmonic and power Long-distance communication LNA low noise amplifier

[Communication interface]:stamp hole

[Transmitting power]:37dBm

[Communication distance]: 20km

[Receive gain]:15dBm

[Introduction]:E21-230G37S is a pure hardware RF medium power amplifier (PA) with a maximum output power of 37dBm and a frequency range of 220 to 236MHz. It has a built-in LNA low noise amplifier and uses high-quality PA chips + unique design solutions to greatly improve PA working efficiency and enable continuous data transmission at an ambient temperature of -40 to +85 degrees. It has built-in filters, limiters, and low noise coefficients to improve the receiving channel's receiving sensitivity and extend the communication distance.
