Its extremely small 4x4mm package makes it ideal for today’s extremely small data enabled phones. Its RF performance meets the requirements for products designed to IS-95/98 standards. The TQM7138 provides the capability to be operated in one, two, or continuous quiescent current modes. In digital quiescent current mode operation, the TQM7138 is controlled from the base-band processor using a CMOS compatible ICQ voltage control voltage. Overall current consumption of the device is minimized by selecting the lowest ICQ state available for each power output level. RF input and output matching is included within the module; therefore, minimal external circuitry is required. The TQM7138 gives excellent RF performance with low current consumption resulting in longer talk times in portable applications. The small 4mm square surface mount package is ideal for new generation small and light phones.

The TQM7138 is a two stage SiGe HBT power amplifier module in Generally, the power supply source impedance should be kept as a cascade configuration intended for use in CDMA Cellular band low as possible, preferably below 0.1 ohms total. Most battery handsets. technologies used in cellular telephones will support a low source impedance, but it may be necessary to supplement this in some Operation designs with an low ESR capacitor. Ceramic or tantalum The operation modes of the TQM7138 are determined based on capacitors of approximately 10 micro-farads work well for this the setting of VCNTRL and VREF. The truth table below defines the requirement. operating mode. Also, if the TQM7138 will be used in continuous bias mode VCNTRL must be connected on the circuit board to ground. The application circuit includes 0.1 µF capacitors at each of the PA control lines and VCC lines to ensure proper RF bypassing. Depending on the phone board layout and circuit bypassing in other areas of the phone, some of these components may not be Operating VCNTRL1 VREF Mode High Power Low >2.7VDC Low-Power High >2.7VDC Continuous Low ~1.9 to Bias Off 3.0VDC Low 0VDC necessary. There are a number of VCO signals and IF signals used in a given phone design, so it is important to protect the PA module from interfering signals and to limit any interference coming from the PA itself. Care should be taken when removing any of the RF bypassing components. One final area of concern is with excessive bypassing. If too large a value of bypassing capacitor is used on any of the control lines, it could reduce the frequency response of that control line to the point where a specification failure could occur. Please be sure that the logic lines and regulated supply lines driving the power Application amplifier control lines are adequate to supply peak current The applications circuit for the TQM7138 is very simple since most requirements of the bypassing capacitors chosen on the control of the critical components are included inside the module. There lines. are several important considerations when using the module in a phone design. First of all, it is important that the source impedance of the VCC power supply be very low. This is because the high current demand during the modulation peaks of the CDMA waveform can introduce voltage ripple at the symbol rate that will introduce additional inter-modulation distortion or Adjacent Channel Power distortion at the output of the power amplifier. If the power amplifier has a quiescent current of 100 mA and a peak current demand in excess of 1 amp, it is possible to see 900 mA change in the current required from VCC as the modulated signal moves from one extreme to the other. If the power supply source One Bias State Operation The TQM7138 can be operated using one bias state. If this mode is selected, VCNTRL should be connected to ground. Continuous Bias-State Operation The TQM7138 can be operated in continuous bias mode in which the VREF voltage is varied from ~1.9V to 3.0V to set the PAM quiescent current as appropriate for the desired output power level. In this mode, VCNTRL should be connected to ground on the phone board. Specific application circuit information for this mode is available upon request.
