MAX2233EEE+, РЧ усилитель, ISM полоса, 800МГц до 1ГГц, 23.9дБ усиление, 2.7В до 5.5В, QSOP-16

The MAX2233EEE+ from Maxim Integrated Products is a 900MHz ISM-band, 250mW power amplifier with analogue or digital gain control in 16 pin QSOP package. This low voltage, silicon RF power amplifier is designed for use in 900MHz ISM band. It is powered directly from a 3-cell NiCd or a 1-cell Lithium-Ion battery. Device typically delivers 250mW (+24dBm) of output power at 915MHz from a single +3.6V supply or 150mW (+22dBm) from a single +2.7V supply. At +24dBm output power, power-added efficiency (PAE) is 44%. The MAX2233 provides 24dB of gain which is adjustable over a continuous 24dB span in two 10dB steps via the 2bit programmable gain-control DAC of the MAX2233. It feature a low power shutdown mode which typically draws less than 1µA of supply current saving power during ‘idle slots’ in time-division multiple-access (TDMA) systems. It is used in 900MHz ISM band, digital cordless phones, wireless data, FM analogue transmitters and 868MHz European ISM band.
