MAX2363EGM-TD 双频段正交发送器芯片，用于移动电话，高速数据调制解调器，卫星电话，无线局域网(WLAN)

The MAX2361 dual-band, triple-mode complete transmitter for cellular phones represents an integrated and architecturally advanced solution for this application. The device takes a differential I/Q baseband input and converts it up to IF through a quadrature modulator and IF variable-gain amplifier (VGA). The signal is then routed to an external bandpass filter and upconverted to RF through an image-reject mixer and RF VGA. The signal is further amplified with an on-chip PA driver. An IF synthesizer, an RF synthesizer, a local oscillator (LO) buffer, and a 3-wire programmable bus complete the basic functional blocks of this IC. The MAX2363EGM-TD supports single-band, single- mode (PCS) operation. The MAX2365 supports single- band cellular dual-mode operation.

The MAX2361 enables architectural flexibility because of its two IF voltage-controlled oscillators (VCOs), two IF ports, two RF LO input ports, and three PA driver output ports. The devices allow the use of a single receive IF frequency and split-band PCS filters for optimum out-ofband noise performance. The low-noise PA drivers allow up to three RF SAW filters to be eliminated. Select a mode of operation by loading data on the SPI™/QSPI™/MICROWIRE™-compatible 3-wire serial bus. Charge-pump current, IF/RF gain balancing, standby, shutdown plus additional functions, are also controlled with the serial interface.

The MAX2361/MAX2363EGM-TD/MAX2365 come in a 48-pin TQFN-EP and QFN-EP package and are specified for the extended (-40°C to +85°C) temperature range.
