Product Description
The RF3198 is a high-power, high-efficiency power amplifier module with
integrated power control. The device is a self-contained
7mmx7mmx0.9mm lead frame module (LFM) with 50Ω input and out-
put terminals. The power control function is also incorporated, eliminating
the need for directional couplers, detector diodes, power control ASICs
and other power control circuitry; this allows the module to be driven
directly from the DAC output. The device is designed for use as the final RF
amplifier in EGSM900 and DCS handheld digital cellular equipment and
other applications in the 880MHz to 915MHz and 1710MHz to 1785MHz
bands. On-board power control provides over 50dB of control range with
an analog voltage input; and, power down with a logic “low” for standby
operation.
