Abstract :
Advantages and disadvantages of the lumped parameter and distributed parameter approaches in UHF RF amplifier design are comparatively studied. In the UHF range of RF up to 1000 MHz, RF amplifiers are designed and fabricated using lumped parameter and distributed parameter approaches. The lumped parameter approach is advantageous due to cost effectiveness and suitability for small quantity production. This approach suffered larger discrepancies with regard to amplifier performance at the first iteration. This is mainly due to uncountable spurious responses. The distributed parameter approach offers consistent performance in RF amplification, and is suited for large quantity production. Iteration and fabrication takes more time, and are more expensive for small quantity production. The amount of discrepancy between the design and the performance at about 1000 MHz of both approaches at the first iteration is documented
