MAX2235 +3.6V, 1W Auto Power Amplifier for 900MHz Applications

MAX2235 +3.6V, 1W Autoramping Power Amplifier for 900MHz Applications MAX2235 silicon RF power amplifier (PA) is designed for use in the 900MHz frequency band. It operates directly from a single +2.7V to +5.5V supply, making it suitable for use with 3-cell NiCd or 1-cell Li-Ion batteries. The device delivers +30dBm (1W) typical output power from […]

Schema Timer for Intervals

Schema timer for intervals of 5 to 30 minutes incremented in 5 minute steps. Timer function to activate an output with a time interval can be set. Done via the timing of setting the value (preset value). The timer will work if given the input and a clock pulse. For the clock pulse is supplied […]

Need a VHF/UHF TV signal amplifier schematics diagram? should have a high gain with low noise?

Nish asked: some websites give details with out the schematic digram or ask money for the diagram. (eg. www.ramseyelectronics.com give full details other than the schematic diagram, which is a must when building a circuit as a beginner)
