It has three different modes: High Gain, Low Gain (Bypass) and Disabled. The IC is programmable through the Gain and Enable pins. The logic truth table is given in Table 5. In these application examples a balance is made between the competing RF performance characteristics of ICC, NF, gain, IP3 and return losses with unconditional stability. Conjugate matching is not used for the input or output. Instead, matching which achieves a trade-off in RF performance qualities is utilized. For a particular application or spec requirement, the matching can be changed to achieve enhanced performance of one parameter at the expense of other parameters. MC13821 Data Sheet: Technical Data, Rev. 1.5 10 Freescale Semiconductor Application Information Application information for 1575, 1960, 2140 and 2400 MHz are shown. For each application, two current drain examples are provided. Typical RF performance is shown for two values of bias resistor R1: 1.2 kΩ and 2 kΩ, see Table 6, Table 7, Table 8, and Table 9. These two current drain states offer variation in intercept point, gain, and noise figure. For 1960 and 2140 MHz, additional application circuits are shown. These demonstrate specific performance characteristics and utilize varying input and output matches and different biasing resistors. Measurements are made at a bias of VCC = 2.75 V. Freq. spacing for IP3 measurements is 200 kHz. Non-linear measurements are made at Pin = -30 dB. The board loss corrections for these boards are: Input 0.16 dB, Output 0.2 dB. Gain and NF results incorporate these corrections in order to better reflect the actual performance of the device. 3.1 1575 MHz Application This application circuit was designed to provide NF < 1.2 dB, S21 gain > 18 dB, OIP3 of 18 dBm with S11 better than -10 dB and S22 better than -10 dB at 1575 MHz with unconditional stability from 100 MHz to 10 GHz. Typical performance that can be expected from this circuit at 2.75 V VCC is listed in Table 6. The component values can be changed to enhance the performance of a particular parameter, but usually at the expense of another. Two variations of the circuit are realized for different requirements for IP3 and ICC. Values of external resistors R1 and R2 are varied to adjust ICC and IP3.

By varying the value of resistor R1, the current draw and the IP3 performance of the device can be tailored for a particular application. Shown here are four variations of the circuit for different IP3 and ICC requirements. The input and output matches are also changed on some circuits to demonstrate different NF and gain performance. Typical performance that can be expected from this circuit at 2.75 V VCC is listed in Table 7. Two variations of the circuit utilize different matches. For all circuits the match consists of a highpass match on the output and a simple inductor-capacitor network on the LNA input.

Resistor values for R1 and R2 are varied to adjust ICC, which also adjusts IP3 performance. Matching component values can be changed to enhance a particular parameter, but usually at the expense of another. Typical performance that can be expected from this circuit at 2.75 V VCC is listed in Table 8. Three variations of the circuit are realized for different requirements for IP3 and ICC. The same matching networks are used on the 2140 MHz circuit as on the 1960 MHz application circuit, with a highpass match on the output and a simple inductor-capacitor network on the LNA input.
