(SOT-363) Definitive Data - Motorola reserves the right to change the Produc tion detail specifications as may be required to permit improvements in the design of its produc t. © Motorola, Inc., 2003. All rights reserved. The MBC13720 is a high IP3, low noise amplifier designed for 400 MHz to 2.4 GHz multistandard wireless applications. The input and output match is external to allow maximum design flexibility. The LNA has two selectable current settings as well as standby mode. The LNA will operate from a 2.5 to 3.0 V supply. The MBC13720 is fabricated using Motorola's Advanced RF BiCMOS process with the SiGe:C option and housed in an ultra small SOT-363 surface mount package.

3 Application Information
The MBC13720 SiGe:C LNA is designed for applications in the 400 MHz to 2.4 GHz range. It has four different modes; Low IP3, High IP3, Bypass, and Standby. The IC is programmable through the Enable 1 and 2 pins. In Low IP3 mode, the current consumption is optimized. Current consumption is higher in High IP3 mode to boost the intercept point performance. The gain difference between Low IP3 and High IP3 modes is typically 1.0 dB and typically the Low IP3 mode has a slightly better noise figure performance. The internal bypass switch is designed for broadband applications. One of the advantages of the MBC13720 is the simplification of matching network in both bypass and amplifier modes. The bypass switch is designed such that the changes of input and output return losses between bypass mode and amplifier mode is minimized. As a result, the mismatch at the LNA input and output is minimized and therefore, the matching network design is simplified as well. In the design of the external matching network, conjugate match condition does not necessarily provide the best noise figure performance. Balancing between noise figure, gain, and intercept point is the major design consideration. Typical circuits are provided in Figures 2 and 3 for 1.9 GHz, 2.4 GHz and 900 MHz applications. In Figure 2, it shows the typical application circuit at 1.9 and 2.4 GHz. The noise figure, input intercept point, gain, and return losses are optimized. L2 and C2 act as a low frequency trap to improve the input intercept point. The noise figure measured on this board is 1.4 dB (in Low IP3 mode) at 1.9 GHz, including the external components, connectors, and PC board. The input third order intercept point is 10 dBm (in High IP3 mode). Table 9. High IP3 Noise Parameters (Continued) (VCC = 2.7 V, EN1 = High, EN2 = Low) Freescale Semiconductor, Inc.

In Figure 3, the typical application circuit at 900 MHz is shown. The input low frequency trap again is used to maximize the input intercept point. It has moderate IP3 performance and high gain. For higher IP3, Figure 4 shows the application circuit with feedback network. Capacitive feedback method is used to reduce the gain and therefore increase the 3rd order input intercept point. The feedback circuit is designed to provide unconditional stability. The corresponding PCBs are shown in Figures 5 through 10. Typical characteristics of the application boards are shown in Table 10.
