Functional Description

Supply Voltage

The IC is designed for a supply-voltage range of V to V. As the IC is internally stabilized, the performance of the circuit is nearly independent of the supply voltage.

Input Impedance

The input impedance, ZRFi, is about 700 with an additional capacitive component. This condition provides the best noise figure in combination with a matching network.
3rd Order Intercept Point The voltage divider, RP/R1, determinates both the input and output intercept point, IIP3
and OIP3. If the value of RP is infinite, the maximum value of IIP3 reach about -4 dBm.

The IP3/RP characteristics are shown in Figure 3 and Figure

Output Impedance and Intercept Point

The output impedance is shown in Figure 11 on page Both low output impedance and a high intercept point are defined to a high value of RP.

Current Consumption, IS

Depending on the chosen input and output conditions of the IC, the current consump-
tion, IS, is between 4 mA and 10 mA. The current consumption in dependence of RP is shown in Figure 6 on page

Power-up Output Symmetry

This feature provides extended battery lifetime. If this function is not used, pin 8 has to be connected to VS pin

The symmetry of the load current can be matched and thus optimized for a given load impedance.

Absolute Maximum Ratings

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
