The F159V is a Dual-Path Integrated TRx IC that has an operating frequency 范围 of 450MHz to 2800MHz. The device provides two independent transmit paths each with 18.3dB typical maximum gain with corresponding output noise floor of -142.5dBm/Hz, +31dBm OIP3, and +14dBm output P1dB designed to operate with a single +3.3V supply while consuming only 685mA DC current. Each signal path includes a quadrature modulator, voltage variable attenuator (VVA), digital 步 attenuator (DSA), and a fixed gain amplifier. The device 支持s a total of 32dB VVA adjustment 范围 using a SPI-controlled 11-bit DAC, and each DSA has 31dB gain control 范围 in 1dB 步s using SPI control.
An on-chip frequency synthesizer is shared by both paths and is optimized for use in multi-carrier, multi-mode FDD and TDD base station transmitters achieving GSM-grade performance. The synthesizer offers both an integer mode and fractional mode. It requires an external loop filter and an external reference oscillator in the frequency 范围 of 10MHz to 250MHz.
The F159V is packaged in a 10mm x 10mm, 68-pin QFN with 110Ω differential drive from external I/Q DACs and single-ended 50Ω RF output impedance for ease of integration into the signal-path lineup for each of the two transmitter paths. Each path has independent power supply control thereby allowing optimum power efficiency.
