MRFIC0954 7 motorola rf/if device data applications information design philosophy the MRFIC0954 has three operating states, enable, standby, and disable. these states are controlled by the truth table shown in table 1. the device is fully operational during the enable state and the bias level can be selected. a high bias current for cdma or a lower bias current for analog (or cdma at lower powers) can be selected via the fm/cdma pin. in the high current cdma mode, the quiescent current is increased to maximize the linearity of the device. in the lower current bias, the quiescent current is optimized for efficiency in the analog mode. this lower bias point is also useful in lower power cdma operation. the standby mode can be used to reduce current consumption during voice activity factoring. in the standby mode, the lo buffer remains on to prevent vco pulling and the bandgap reference bias circuit remains on to assure rapid device turn on. current consumption in standby mode is 10 ma typical. the disable mode is used to turn the MRFIC0954 completely off. leakage current in this mode is only a few microamps. the mixer is a doublebalanced agilbertcello design with a balanced lo buffer amplifier. the input and output of the mixer are differential. however, the linearity is high enough to tie one output to v cc and use the other as a singleended output. used this way it provides around 7.0 db of gain and typically draws 20 ma quiescent current in cdma mode and 16 ma in analog mode. an external filter is required between the mixer and rf agc amplifier to reduce rx band noise. figure 1 shows the applications circuit for the MRFIC0954. in this circuit, the if ports of the mixer have been matched to 50 w for testing purposes. in the actual application, the differential if ports of the mixer would be impedance matched to an if saw filter. the differential impedance of the mixer if ports is 1600 w . the rf output of the mixer is configured as a single ended output. dc current to the open collector output of the mixer is provided by inductor, l6 (6.8 nh). inductor l6 is also part of the matching circuit with c13 (1.6 pf), c14 (1.3 pf) and c15 (100 p). the rf agc amplifier is a singleended cascode design employing the standard acurrent steeringo method of gain control. it's ground is brought out through pin number 15 so inductance can be added to degenerate the gain for a lower noise floor. with 2.0 to 3.0 nh of external inductance, the maximum gain is around 13 db. it typically draws 9.0 ma quiescent current in cdma mode and 3.0 ma in analog mode. the rf v cntrl signal is buffered with an onchip opamp then preconditioned with temperature compensation and db/v linearization before being applied to the rf agc amplifier. inductor l3 (6.8 nh) and capacitor c6 (100 pf) are for the interstage match between the rf agc and the exciter amplifier. the exciter amplifier is a simple common emitter design. it is grounded directly to the exposed pad which results in 12 db of gain. it typically draws 24 ma bias current in cdma mode and 8.0 ma in analog mode. inductor l4 (6.8 nh), capacitor c7 (4.3 pf), and c9 (100 pf) provide the output matching. l4 also provides a dc current path for the open collector output. noise power considerations in cdma systems, the handset is required to dynamically adjust its output power to specific levels. this requires a dynamic range of as much as 90 db from the transmitter. another key performance specification in cdma systems is the output noise power, both in band and out of band. noise power specifications has caused the noise figure of the transmitter to become an important system consideration. the cascaded noise figure of the transmitter can be analyzed with the same equation used in receiver analysis. the only difference is the noise source is from the transmitter (modulator) instead of the atmosphere. noise source gain = noise figure = g1 nf1 g2 nf2 g3 nf3 nf cascaded nf 1 nf 2 1 g 1 nf 3 1 g 1 g 2 this equation above shows that the cascaded noise figure is better if the gain is higher and the noise figure is lower for the stages close to the noise source. for this reason, it is advantageous to implement some of the gain control of a cdma transmitter in the rf section. the MRFIC0954 integrates a rf agc amplifier after the upmixer to improve the overall noise figure of the transmitter. if better noise figure from the mixer is required, the mixer rf output can be operated differentially with the addition of a balun. operating the mixer differentially will provide some noise cancellation and reduce the noise figure by 5.0 db. shown below is a lumped element balun that is effective in the cellular transmit band of 824 to 849 mhz. 19 18 17 v cc rf out 33 nh 15 nh 100 pf 2.0 pf
