APPLICATIONS INFORMATION DESIGN PHILOSOPHY The was designed for low cost and flexibility. Low cost was achieved by minimizing external components and using an SOIC package. Flexibility was achieved by allowing the bias current to be externally adjustable resulting in a broad range of output power capability. The bias pin can be ramped to reduce AM splatter in TDD/TDMA systems and can be used to trim the RF output power. THEORY OF OPERATION The input port is internally matched to ohms. Return loss is typically 6 db in the MHz range. The output port is nearly ohms but is an open collector and therefore requires an external bias inductor. Using an RF choke will result in a 2 db output return loss. However, a nh inductor will improve it to db. A nh inductor is small enough in value to be printed on the board. DC blocks are required on the input and output. Values of pf are recommended. Supply decoupling must be done as close to the IC as possible. A pf capacitor is recommended. A series RF choke is recommended to keep the RF signal off the supply line. A nf decoupling capacitor is recommended on the Vbias line but does not need to be very close to the IC. The Vbias pin can be used several ways. Tying it directly to VCC will maximize the bias current which will maximize linearity. Adding a series resistor will reduce the bias current which will improve efficiency. Figure 9 shows the efficiency versus output power with Vbias tied to VCC. The series resistor will cause these curves to shift to the left. The RF output power can be trimmed by using a variable resistor. The Vbias pin can also be used to power down the IC or, in the case of TDD/TDMA systems, to ramp the IC. By applying a linear ramp voltage, such as the one provided by the MRFIC, it has been demonstrated to meet the CT2 Common Air Interface splatter specifications. The is internally temperature compensated. For input powers of. to dbm the output power temperature variation is typically less than.2 db from 3 to + C.
