a fantastic antenna amplifier circuit for the entire VHF broadcast
band (100-175 MHz) which can be successfully built without any special
test equipment that will bring those weak signals into your receiver.
The grounded-gate configuration is inherently stable without any
neutralization if appropriate PCB layout techniques are employed. The
performance of the amplifier is excellent.
The noise figure is
below 2 dB and the gain is over 13 dB. The MAX2633 is a low-voltage,
low-noise amplifier for use from VHF to SHF frequencies. Operating from
a single +2.7 V to +5.5V supply, it has a virtually flat gain response
to 900 MHz. If you have ever wanted to boost the signals received for
Spy Devices - transmitters, etc. this antenna amplifer circuit is the
antenna amplifier circuit you have been looking for.
