saving optimizations of existing discrete transmitter circuits )xqfwlrqdo'hvfulswlrq the PMB2240 is a single-chip transmitter which includes a prescaler for the main oscillator signal and a fixed frequency pll for the if oscillator. the transmitter is designed for use in conjunction with the single-chip receiver pmb2405 and the cmos pll pmb2306. the rf oscillator signal can be supplied from an external source symmetrically as well as unsymmetrically. the oscillator signal can be buffered for off-chip use, depending on a separate power down pin. there is a prescaler by 64/65 for the rf oscillator signal on chip, which can be used to implement a pll together with the pmb2306. the on-chip fixed-pll consists of the system clock divider, the if oscillator signal divider, the phase detector and the charge pump. the if oscillator signal divider is driven by the oscillator on the pmb2405 or by an external discrete vco. the two oscillator signals are combined in the transmit mixer, and the image sideband and other mixing products are suppressed with an external interstage filter. the filtered signal reenters the chip at the modulator inputs lo/lox. the modulator generates two orthogonal carriers which are mixed with the modulation signals i and q in two gilbert multipliers. the phase between the two carriers can be fine-adjusted to 90 (orthogonality) by two external resistors at off1/off2 for best ssb suppression. the outputs of the gilbert cells are added and amplified by a linear output stage. the PMB2240 is designed for digital mobile telephones according to the gsm-standard. the chip can also be used for other digital systems and the dual mode system. as part of the siemens gsm/dcs chipset the derivatives pmb2245 and pmb2247 are offered for the dcs 1800 and dcs 1900 frequency range. *607udqvplwwhu 30%9 the reproduction, transmission or use of this document is not permitted without express written authority. offenders will be li able for damages. all

gsm transmitter PMB2240 contains a number of functions that have been realised with multiple chips earlier: - oscillator signal input balanced or unbalanced - rf-pll prescaler - if-pll dividers and phase detection - tx - mixer - i/q modulator the PMB2240 v1.6 is designed to be used with an external rf oscillator module. on chip this signal is ac-coupled to an internal buffer stage. therefore the rf input is suitable for symmetrical or single ended use. there is no need for an external dc-bias of the rf input. the active parts of the if oscillator are located on the receive chip pmb2405. a buffer bufrx, which can be powered down by pin pdbufrx, is used to transmit the rf oscillator signal to the receiver chip to drive the rf receive mixer. a special input buffer buftx receives the if oscillator signal from the receive chip or an external source. the rf oscillator signal is divided by the integrated 64/65 prescaler which can be connected to the cmos pll circuit pmb2306 for the rf oscillator pll. the supply pin vccpr is a separate prescaler supply, which openes the possilility to run the prescaler and the rest of the rf synthesizer on a supply voltage that is different from the supplies of the rest of the chip. for the if-pll the active oscillator structures on the pmb2405 or an external vco module can be used. the PMB2240 v1.6 contains the digital parts tor the if oscillator pll (fixed-pll): the if- frequency and system clock dividers and a phase detector plus charge pump are integrated to lock the if oscillator to the external system clock. the oscillator signal drives the divider by 2 in front of the transmit mixer. the phase locked if- and rf- signals are converted into the transmit band (e.g. 880 - 915 mhz for gsm) by the tx- mixer. the mixer output signal leaves the chip at mo/mox and passes an external interstage filter to provide suppression of unwanted products. this signal reenters the chip at the modulator input lo/lox. the lo signal is divided into two orthogonal carriers at the transmit frequency. the phase between the two carriers can be fine-adjusted to 90 (orthogonality) by two external resistors at off1/off2 for maximum ssb suppression. the modulator consists of two gilbert multipliers, where the modulating signals i(t) and q(t) are multiplied with the rf-carriers. the outputs of both gilbert cells are added and amplified by a linear output stage. the modulated transmit signal is available at e/ex and is fed into a transmitter power amplifier. *607udqvplwwhu 30%9 the reproduction, transmission or use of this

the rfvco parts. the supply pin vccpr is a separate prescaler supply, which openes the possilility to run the prescaler together with the rest of the rf synthesizer on a supply voltage that is different from the supplies of the rest of the chip gnd4 is a special shielding ground to decrease crosstalk between the separately supplied blocks. gnd5 collects the substrate contacts in the modulator and mixer. it is recommended to connect all gnd pins to a common gnd on the board. in the following figure the chip schematic is partitioned according to its supply rails. *607udqvplwwhu
