900 MHz PAGING POWER AMPLIFIER Si MONOLITHIC INTEGRATED CIRCUIT
This integrated circuit is intended for two-way paging applications and for other Industrial, Scientific and Medical (ISM) at 900 MHz band applications. The three stage design is implemented in Motorola's low cost, high performance LDMOS process and housed in a low-cost surface mount SOIC package. Input and output matching is implemented off-chip for maximum flexibility while interstage matching is on-chip. A power control pin is included allowing 60 dB dynamic range. * 30.5 dBm Output Power for 3 dBm Input Power at 900 MHz * 32 dB Typ Small Signal Gain * 40% Efficiency Min at 30.5 dBm Output Power * 4.0 to 5.5 Volt Operation * Low-Cost, Low Profile Plastic SOIC Package * Order MRFIC0914R2 for Tape and Reel. R2 Suffix = 2,500 Units per 16 mm, 13 inch Reel. * Device Marking = M0914

APPLICATIONS INFORMATION
DESIGN PHILOSOPHY The MRFIC0914 three stage LDMOS integrated power amplifier was designed for low cost and flexibility. While the target application was two-way paging, the device can be used in a variety of 800 to 1000 MHz applications and it is particularly suited to burst mode digital transmissions with constant envelope modulation schemes. Only one supply is required. The VCNTRL pin allows the setting of the gate bias of the three stages simultaneoulsy for optimum gain and efficiency and serves as a transmit control with more than 60 dB dynamic range. CIRCUIT DETAILS In Figure 1, the 900 MHz applications circuit, note that each stage has a separate supply pin, including the RF Output for the third stage. Care should be taken in bypassing these supply connections to avoid low frequency oscillation. Chip capacitors should be mounted as close to the leads and ground vias as possible. Ground vias should be provided close to the indicated ground leads as well. L1 is a bias choke supplying the third stage and could be replaced with a quarter wave line or air-wound inductor. EVALUATION BOARDS Evaluation boards are available for RF Monolithic Integrated Circuits by adding a "TF" to the device type. For a complete list of currently available boards and ones in development for newly introduced products, please consult your local Motorola Distributor or Sales Office. RF performance is sensitive to the output matching network. C9 and L3 form a second harmonic trap which enhances efficiency. Placement of C3 along the 50 line at the device output is critical to gain and efficiency. L2, the input matching inductor, is optional. Without this inductor, the input match is still typically better than 2:1 VSWR. It should be note that Figure 1 does not portray the parasitics of the chip components nor their solder mounting pads. The board material is 18 mil dielectric thickness FR4. The impedances shown in Table 1 were derived from circuit characterization and are given as an aid to original designs.
