Application information.
DECT SINGLE ENDED POWER AMPLIFIER
When used as a single ended power amplifier, please refer to fig.7 and the test board fig. 8.
The 50
source impedance is converted to 50
differential with an LC-CL structure. Two series capacitors AC-couples the signal
to the input of PBL403 09. Suitable value of the capacitors is 1 to 5 pF in order to compensate for series inductance of the PCB and
package. Input impedance of the PBL403 09 is 50
differential.
The ideal collector load of the open collector RF output of PBL403 09 is about 11
per side. A matching and combination network to
50
single ended case is shown in fig. 7. A shunt capacitor (2.7 pF) transforms each output to 50
. Both 50
outputs are AC coupled
and then combined with an LC-CL structure to a 50
single ended output.
