Typical Single-Band Application Circuit The AJAV-5505 is the world’s first 3G Band V power amplifier (PA) implemented in a standard CMOS process. The AJAV-5505 delivers low current and integrates TX filtering that produces the best noise in the industry. Only a single RF bypass capacitor is required, enabling a very low billof-materials (BOM). The AJAV-5505 is fully compliant with W-CDMA, HSPA, and HSPA+ standards through 3GPP Release 7 and supports Power Class 3 and 4. Figure 1 shows the typical application circuit. The AJAV5505 supports three power modes controlled by a standard CMOS interface enabling a direct connection to the baseband with no level shifters. The VEN, VM0 and VM1 power control pins are high impedance with logic levels defined in Table 2. The AJAV-5505 may be powered by a single direct connection to the battery, or controlled with an external DC/ DC converter. All power supply current flows through pin 10. Pin 1 is a low current input that can be directly connected to VBAT or any other high level signal. No external switches, isolation inductors, or bypass capacitors are required on Pin 1. 4 Standard RF practice should be followed for the PCB layout of the RF traces for pins 2, 6, 8, and 9. Multiple vias should be placed underneath the GND paddle to create a low resistance path to ground and to ensure good heat conduction. Refer to Application Note 5565, (AV02-4080EN) AJAV5xxx PCB Guidelines, for additional information. The AJAV-5505 features an integrated directional coupler that can be daisy-chained through the CPLI and CPLO ports. For best performance, at least one port should see a 50 Ω path to GND. The CPLI port accepts an RF input or can be terminated. The CPLO port provides the coupled RF output that can be passed to the RF detector, terminated, or passed to the next PA in the daisy chain. The AJAV-5505 includes integrated TX filtering that ensures excellent receiver sensitivity. As the RF signal passes through the PA, the unwanted out-of-band noise produced by the transceiver is filtered out. Furthermore, the thermal noise at the PA output is greatly reduced below the level of a conventional GaAs PA. The resulting signal at the output of the AJAV-5505 is spectrally very clean, ensuring the best receiver sensitivity and producing minimal interference to other radios in the system.
