Functional overview

In the TX direction, the MPT-HLC Transceiver converts Ethernet packet data from the 
EAS (Ethernet Access Switch - P8ETH or EASv2) card MPT-HL port or Core-E or CorEvo 
Ethernet port into a modulated IF output signal. The modulated IF signal is converted into 
a RF signal which is amplified by the Power Amplifier (PA) and routed through a band-
pass filter to the antenna.

In the RX direction, the MPT-HLC Transceiver card amplifies the incoming RF signal. 
Converts the RF signal into a first IF signal. The first IF signal is then converted to a second 
IF signal. The second IF signal is filtered, demodulated, and converted into Ethernet packet 
data. The Ethernet packet data is then sent to the EAS card MPT-HL port.

For each frequency two different versions of the MPT-HLC are available and supported in 
this release: standard and space diversity version. The space diversity version includes a 
second receiver and a baseband combiner, which provide a combination of main receiver 
and second receiver signals.
