"wide band amplifiers are those amplifiers which amplify ah a higher band width or in short the frequency range is very wide.. by VHF indicates Very High Freaquency- denotes hiher ranges of freaquency 30MHZ to 300 MHZ these amplifiers are working on these reagions so as we need amplifiers of these range normally the internal capacitace of high freaquency switching will affect the freaquency due to internal juction capacitance(MILLER CAPACITANCE)will attenuate the freaquency so much. to avoid this problem we have to use the high freaquency transistors. normally BFW195 are used for small range of aplications commonly" WITH LOVE MADHAV "MADHAVNAMBIARCK@YMAIL.COM"
Yes
Yes.
NO. Transformer coupling gives the higher gain in case of amplifer.
A walkie-talkie refers to a portable radio. VHF range is usually 136 to 172 mhz and a portable will pick up if tuned to this range.
the high frequency, it is in VHF band.
You need a VHF radio antenna, a VHF radio receiver and of course a station broadcasting on the VHF frequency.

The correct spelling is "amplifier."
Yes
A VHF ocsillator is a very high frequency ocsillator (30-300MHz). It oscillates (swings back and forth) at a VHF frequency.
VHF is in the range 30 to 300 MHz.
CQ VHF Magazine was created in 1996.
VHF radios work by the line of sight principle
Because VHF signals have a line of sight limitation.
