This UHF wideband amplifier (Ultra High Frequency amplifier) has a total gain of 10 to 15 dB in the 400 – 850 MHz domain frequency so it can be used where the tv signal is weak. For this UHF antenna ...

These were tuned to the desired channel and they attenuated signals 14 or 15 channels higher than the desired channel. The FCC established a minimum spacing between analog TV transmitters on channel ...

So what about better RF selectivity? Well that would require high Q-tuned circuits between the antenna and the RF amplifier and between the RF amplifier and the mixer. These tuned circuits use ...

The company also created p-type (positively charged) and n-type (negatively charged) semiconductors needed to form of low-power complementary metal oxide semiconductor (CMOS) circuits. It additionally ...
