Product Description
The RF6509 integrates a complete solution in a single Front-End Module (FEM) for
AMR and Smart Grid solutions. The RF6509 integrates a 915MHz PA, some trans-
mit (Tx) filtering, input and output switches, a Tx or receive (Rx) attenuation path,
and an LNA with bypass mode. The RF6509 has a single-ended input and output
for optimized ease of use and implementation. The pin-out of the FEM enables
users to implement additional filtering external to the module, if needed. The device
is provided in a LGA, 32 pin, 8mm x 8mm x 1.2mm package.

Ground.
RF output to enter the Rx filter (if used), 50 nominal impedance.
Logic input to the Tx Switch arm 2 , selects/deselects thru path if Logic high/low respectively, see truth table.
Logic input to the Tx Switch arm 1, selects/deselects Low Noise Amplifier if Logic high/low respectively, see
truth table.
Ground.
RF output to Antenna for the Tx/thru path and RF input from Antenna for the Rx/thru path, 50 nominal imped-
ance.
Ground.
Logic input to the Tx Switch arm 3, selects/deselects PA if Logic high/low respectively, see truth table.
Not connected.
Ground.
Collector power supply for Power Amplifier. Nominal 3.6V.
Ground.
Not connected.
Power supply for the PA Bias Network. Nominal 3.6V.
Ground.
Voltage set to PA Bias Level. Nomial 2.85V.
Collector power supply for PA driver stage. Nominal 3.6V.
Not connected.
Not connected.
RF Input to the PA, 50 nominal impedance, needs to be connected externally to PA IN to SWITCH PIN through
as short as possible 50 transmission line.
PA input to be connected to the Rx Switch through this pin, 50 nominal Impedance.
Logic input to the Rx switch arm 2, selects/deselects Thru path if Logic high/low respectively, see truth table.
Logic input to the Rx switch arm 1, selects/deselects PA if Logic high/low respectively, see truth table.
Ground.
Transceiver IN/OUT.
Ground.
Logic input to the Rx switch arm 3, selects/deselects LNA if Logic high/low respectively, see truth table.
Not connected.
Collector power cupply for LNA. Nominal 3.0V.
A logic low selects the high gain mode of the LNA, logic high selects the low gain mode.
Voltage to set the bias of the LNA, nominal 3.0V, can be adjusted to shut the LNA off or set the quiescent current
of the LNA to desired level.
RF input to LNA, nominal impedance 50, the Rx filter output should be connected to this pin, If Rx filter is
bypassed, pin 2 should be connected to this pin htough an external 50 transmission line as short as possible.
