product description 2 - 2 pmb 2208 preliminary wireless components confidential specification, august 1999 2.1 overview the pmb 2208 contains a direct quadrature modulator and an up/down-conver- sion mixer with corresponding bias circuitry. the modulator splits the signal at the lo/lox input into two orthogonal carri- ers. the frequency of these carriers is half of the lo/lox input frequency. the carriers are multiplied with the baseband modulation signals at the a/ax and b/bx inputs. the outputs of the multipliers are added and amplified by a linear output stage. the modulated signal is available at the e/ex output. a reference voltage is available at the tref output, which can be used to bias the base- band inputs. the mixer combines the signals at the rf/rfx and if/ifx inputs; the resulting signal is available at the mo/mox output. the if/ifx input is suitable for the lower-frequency signal because of its linear transfer function to the output. the higher-frequency signal is applied to the rf/rfx input, which operates in switched mode. in a typical application, the output signal of the modulator is band-pass filtered and then fed to the if/ifx input of the mixer. the modulator and mixer have separate power supplies, and can be powered down independently. the power-down concept enables the modulator to be used with or without the mixer. 2.2 features n direct quadrature modulator and up/down-conversion mixer on one chip n modulator: - lo input frequency range from 200mhz to 550mhz corresponds to an out- put frequency range from 100mhz to 275mhz - generation of orthogonal carriers without external elements and without trimming - typ. 48db carrier suppression with 1v pp baseband level - typ. 49db ssb suppression with 1v pp baseband level - typ. 51db rejection of third-order intermodulation products with 1v pp base- band level - low output noise floor n mixer: - double-balanced gilbert cell - rf and if frequency range from dc to 2.5ghz - typ 39db carrier suppression -low noise

functional description 3 - 6 pmb 2208 preliminary wireless components confidential specification, august 1999 3.5 circuit description the modulator performs a direct quadrature modulation. the lo signal is con- nected to an emitter-coupled transistor pair. the lo signal is split internally into two orthogonal carriers at half of the lo/lox input frequency. the accuracy of the internal 90 phase shift requires a balanced input signal and depends on the accuracy of the 50% duty cycle of the lo/lox signal. the modulator has two gilbert cell mixers, in which the baseband modulation signals at the a/ax and b/bx inputs are multiplied with the orthogonal carriers. the outputs of the two gilbert cells are added and amplified by a linear output stage. the modulated transmit signal is available at the high-impedance, open-collector output e/ex. it can be band-pass filtered and fed to the if/ifx input of the mixer. at the tref output, a reference voltage is available, which should be capaci- tively decoupled to ground. tref can be used to set the dc bias of the base- band inputs using external resistors. alternatively, the dc level can be set independently of tref, provided it is within the specified operational range. the up/down-conversion mixer is a fully-balanced gilbert cell. the transfer function from the low-impedance emitter input if/ifx to the output is linear for input levels below the 1db compression point. for improved intermodulation, the mixer current can be increased with external resistors to ground at if/ifx. the high-impedance input rf/rfx is directly connected to the bases of the switching transistors. the input level should be high enough to ensure proper switching. the output signal of the mixer is available at the high-impedance, open-collector outputs mo/mox. the modulator and the mixer have separate supply and power-down pins: vcc1, pd1 for the modulator and vcc2, pd2 for the mixer. applying a logic low to pd1 or pd2 powers down the corresponding part of the chip, including its bias circuitry. depending on the application, the power-down pins can be combined or separately fixed to supply rails.
