RF amplifier circuit design RF Amplifier with MOSFET K2668, 2570, 2053 circuit diagram

MAX2264/MAX2265/MAX2266 power amplifiers are designed for operation in IS-98-based CDMA

The MAX2264/MAX2265/MAX2266 power amplifiers are designed for operation in IS-98-based CDMA, IS-136-based TDMA, and PDC cellular telephones operating in the 900MHz range. When matched for CDMA operation and biased with margin over the adjacent and alternate channel specification (-45dBc/-56dBc), the amplifiers achieve 28dBm output power with 37% efficiency (MAX2265). At +16dBm output-a very common power […]

Lights & LED Circuits & Schematics LDR

An ordinary automatic room power control circuit has only one light sensor. The circuit uses two LDRs which are placed one after another (separated by a distance of say half a metre) so that they may separately sense a person going into the room or coming out of the room. Outputs of the two LDR […]
