Control Level: Automatic, which automatically detects the input power level to
achieve automatic transmission and reception. The transmission
starts when the input power reaches 22 dBm, and it switches to
reception when it drops below 10 dBm (or the "EN" terminal can be
externally connected to achieve TTL high-level transmission and
low-level reception).
EN 1: Power amplifier transmission state, reception off;
EN 0: Reception state, transmission off (the static current of the
power amplifier is less than 0.15A)
Drawing of the TDD power amplifier module:
Port Description:
1. Since the data transmission radio uses the same port for
transmission and reception, so the ‘RX’ port of this TDD power
amplifier module is left unused. The 'TX' port is the RF port of
the data transmission radio, and the ‘ANT’ port is connected to the
filter to the antenna.
2. 'EN' or 'EN-TR' is the transmission enable mode of the data
transmission radio in non-automatic mode. (in automatic mode and
enable mode, it needs to be set at factory, with 1.8~5V TTL level).
3. '+12V' or 'VDC' is +12~18V power supply. The wire pin pressed by
this inductive capacitor is the negative pole.
4. 'FULL' blue indicator light indicates full power output
indication. When the output power reaches the ALC trigger and
reaches a certain depth, this LED indicator light will light up.
5. 'TX' red indicator light indicates transmission state.
6. 'RX' green indicator light indicates reception state.
7. 'EN-PWR' terminal is only available in the old version. In the
new version, it is generally connected to 12~18V, while '+12V' may
be based on the high-power 80W version and connected to 24~28V.
8. 'FWD' is a backup power detection output terminal. It is usually
left empty and can be modified to be a 12V or 28V power input as
needed.
Frequently Asked Questions:
Q1. Can you make the RF Power Amplifier to be other frequencies?
Output 10W and more?
A:Yes, under certain circumstances,in order to achieve
long-distance transmission, high power output and high efficiency.
It can output a digital power of 10W for use.And we also have
different power amlifiers with 10W,20W,50W etc.
Q2. How long is the warranty?
A: 1 Year warranty and lifetime maintenance.
