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 […]

Making Frequency Modulation circuit

In this case the frequency of the oscillator is determined by the values of the capacitor and inductor: C and L. Notice that I have now added a diode and another capacitor 10C (10 times bigger than C). The oscillations across the ends of L are a sinewave, varying above and below the Gnd (battery […]
