The FEM-10W-PA (FEM) is an advanced L Band Duplex Front End Module designed for use
with high modulation rate TDD COFDM radios.
The FEM contains an LNA in the receive path and a 90 Watt peak PA stage in the transmit
path. Switching between RX and TX mode is via a logic level control line. The PA
is capable of providing in excess of 10Watt (+40dBm) average linear power into 50
Ohms at 1.4GHz.
The FEM requires an RF input of +24dBm to achieve the maximum linear output and a
power source with voltages between 12 to 28V dc, capable of supplying up to 60 Watts
The FEM is housed in a high quality milled aluminium casing which should be bolted
to an additional heatsink, or bulkhead for cooling purposes. A logic level temperature
controlled fan output is provided if additional forced cooling if required.
The FEM can be adapted to operate on other frequencies (subject to minimum order
quantities, or NRE).
L Band Duplex FEM combines a 10Watt (+40dBm Ave) linear PA and LNA in a compact milled
case. (L140mm x W90mm x H21.6mm).
