## IMPEDANCE MATCHING USING STUB

Let us discuss today discuss what is impedance matching and what is stub:

IMPEDANCE MATCHING

A transmission line is matched when the load impedance ,Zris equal to the characteristic impedance ,Z0 of the line that is Continue reading “IMPEDANCE MATCHING USING STUB”

## Input impedance for quarter wave and half wave transmission line

1. Input impedance Zi for quarter wave transmission line

A transmission line is said to be quarter wave transmission line when its length equals quarter wavelength.

That is                                             l=λ/4

Or                                                   l=(2n-1)λ/4 (odd multiple of λ/4)

Or                                                   βl=2π/λ * λ/4                                              [ β=2π/λ]

## ULTRA HIGH FREQUENCY (U.H.F) TRANSMISSION LINES-1

ULTRA HIGH FREQUENCY (U.H.F) TRANSMISSION LINES (TRANSMISSION LINES AS CIRCUIT ELEMENTS)

Ultra High Frequency lines commonly abbreviated as U.H.F lines are one of the types of the transmission lines. Ultra high frequency lines have operational frequency range from 300 to 3000 MHz or wavelength from 100 cm to 10 cm. Continue reading “ULTRA HIGH FREQUENCY (U.H.F) TRANSMISSION LINES-1”
