| Abstract: |
| A novel power divider is designed for the purpose of operating at two
arbitrary frequencies. The circuit parameter design formula is obtained on the b
asis of even-odd mode analysis and microwave network theory and the specific cir
cuit parameters are derived by solving the corresponding nonlinear equations. A
1 GHz/2.6 GHz dual-band power divider is made for verification. Measured res
ults show that the transmission coefficient at the two central frequencies is le
ss than 3.3 dB, return loss greater than 21 dB and port isolation greate
r than 28 dB and it has a good performance in 100 MHz bandwidth of the c
entral frequencies. |
