The JUPITER circuit is designed for use in dual band and dual mode mobile phones (CDMA/AMPS) and meets the requirements for IS-95 when used with other chips from Mitel that form the Planet chipset. JUPITER is an active filter incorporating circuits for receiving both CDMA and FM (AMPS).

The block diagram of the JUPITER filter is shown in Fig. 3. Two tunable active low-pass gyrator filters are designed with balanced I/Q inputs and outputs. CDMA MODE In CDMA mode the filter (F1 on Fig. a 7th order 0.1dB ripple continuously tunable elliptic type with the corner frequency tuned to 690kHz for best stop band attenuation and minimal phase error (in the overall system). Variable gain stages after the filter provide the gain control capability. Overall, each of the CDMA I/Q channels has 45dB nominal voltage gain with the Q channel having ±2dB gain adjustment range. Separate I/Q frequency tuning functions are built into the device. FM MODE In FM mode the same filter is used; however, the biasing is designed such that the current density in the transconductor cells is reduced by a factor of 46, changing the filter's cutoff frequency to 15kHz. The filter characteristic of the main channel filter (gyrator filter) remains the same, i.e. 0.1dB 7th order elliptic. In FM mode additional 2nd order Sallen and Key 0.1dB ripple Chebeyshev filters (F2) are included in the signal path prior to the gyrators. These improve the out-of-band blocking of the overall filter. Different amplifiers are used in FM mode to those used in CDMA mode to enable optimization of the gain distribution in FM mode for current consumption and dynamic range. OPERATION Signal inputs are DC coupled in both CDMA and FM modes. The device modes are selected by CMOS compatible logic signals as shown in Table 2. An external resistor should be connected between RTUNE and ground to set internal currents; a resistor with a tolerance of 65% and a temperature coefficient of less than 100ppm is recommended. VREF (pin 18) should be decoupled to VCC to give optimum supply rejection. A test mode is provided for filter calibration. In this mode, a test signal is applied to the VTEST input (pin 7) with ENTEST held high. The test mode is designed to interface with the PLUTO baseband processor, which can provide the test signal and I/QTUNE voltages and calibrates the filters using an internal auto calibration algorithm. The algorithm generates two test frequencies and calibrates the filters to give the correct attenuation at the upper frequency. The calibration is normally carried out in CDMA mode: the FM filter performance is scaled accordingly. Pins are provided for DC offset control for I and Q channels (I_OFFSET, I_OFFSETB, Q_OFFSET and Q_OFFSETB). In typical operation, the I_OFFSET/Q_OFFSET pins would be controlled by a voltage derived from the baseband processor. However, it is also possible to minimise the DC offset using external components; this is primarily intended for test purposes. These feedback components between IOUT/QOUT and I_OFFSET/Q_OFFSET are shown in Fig. 4 but would not be used in the normal application In test mode, these offset controls are disabled and the offsets are controlled using on-chip feedback. The loop filter for this feedback uses external 10nF capacitors on pins I_OC_TEST/B and Q_OC_TEST/B as shown in Fig. 4.
