This device is designated for use as the frontend section in analog and digital FM systems such as Wireless Local Area Network (LAN), Digital European Cordless Telephone (DECT), PHS, PCS, GPS, Cellular, UHF and 800 MHz Special Mobile Radio (SMR), UHF Family Radio Services and 902 to 928 MHz cordless telephones. It features a mixer linearity control to preset or auto program the mixer dynamic range, an enable function and a wideband IF so the IC may be used either as a down converter or an up converter. Current Regulation Temperature compensating voltage independent current regulators provide typical supply current at 1.0 mA with no mixer linearity control current. Mixer The mixer is a unique and patented double-balanced four quadrant multiplier biased class AB allowing for programmable linearity control via an external current source. An input third order intercept point of 20 dBm may be achieved. All 3 ports of the mixer are designed to work up to 2.4 GHz. The mixer has a 50 single-ended RF input and open collector differential IF outputs (see Internal Circuit Schematic for details). The linear gain of the mixer is approximately -5.0 dB with a SSB noise figure of 12 dB. Local Oscillator The local oscillator has differential input configuration that requires typically -10 dBm input from an external source to achieve the optimal mixer gain. Figure 8.

The PC board is laid out to accommodate all SMT components on the circuit side (see Circuit Side Component Placement View). Component Selection The evaluation PC board is designed to accommodate specific components, while also being versatile enough to use components from various manufacturers. The circuit side placement view is illustrated for the components specified in the application circuit. The Component Placement View specifies particular components that were used to achieve the results shown in the typical curves and tables. Mixer Input The mixer input impedance is broadband 50 for applications up to 2.4 GHz. It easily interfaces with a RF ceramic filter as shown in the application schematic. Mixer Linearity Control The mixer linearity control circuit accepts approximately 0 to 2.3 mA control current. An Input Third Order Intercept Point, IIP3 of 20 dBm may be achieved at 2.3 mA of control current (approximately 7.0 mA of additional supply current). Local Oscillator Inputs The differential LO inputs are internally biased at VCC - 1.0 VBE; this is suitable for high voltage and high gain operation. For low voltage operation, the inputs are taken to VCC through 51 . IF Output The IF is a differential open collector configuration which is designed to use over a wide frequency range for up conversion as well as down conversion. Input/Output Matching It is desirable to use a RF ceramic or SAW filter before the mixer to provide image frequency rejection. The filter is selected based on cost, size and performance tradeoffs. Typical RF filters have 3.0 to 5.0 dB insertion loss. The PC board layout accommodates both ceramic and SAW RF filters which are offered by various suppliers such as Siemens, Toko and Murata. Interface matching between the RF input, RF filter and the mixer will be required. The interface matching networks shown in the application circuit are designed for 50 interfaces. Differential to single-ended circuit configuration is shown in the test circuit. 6.0 dB of additional mixer gain can be achieved by conjugately matching the output of the MiniCircuits transformer to 50 at the desired IF frequency. With narrowband IF output matching the mixer performance is 3.0 dB gain and 12 dB noise figure (see Narrowband 49 and 83 MHz IF Output Matching Options). Typical insertion loss of the Toko ceramic filter is 3.0 dB. Thus, the overall gain of the circuit is 0 dB with a 15 dB noise figure. Figure 9.

The PCB also accommodates a surface mount RF SAW filter in an eight or six pin ceramic package for the cellular base and handset frequencies. Recommended manufacturers are Siemens and Murata. The PCB may also be used without a preselector filter; AC coupled to the mixer as shown in the test circuit schematic. All other external circuit components shown in the PCB layout above are the same as used in the test circuit schematic. 16:1 broadband impedance transformer is mini circuits part #TX16-R3T; it is in the leadless surface mount "TX" package. For a more selective narrowband match, a lowpass filter may be used after the transformer. The PCB is designed to accommodate lump inductors and capacitors in more selective narrowband matching of the mixer differential outputs to a single-ended output at a given IF frequency. . The local oscillator may also be driven in a differential configuration using a coaxial transformer. Recommended sources are the Toko Balun transformers type B4F, B5FL and B5F (SMD component). 6 MOTOROLA ANALOG IC DEVICE DATA MC13143 Figure 11.
