Cascade RF Electrical Characteristics (Cellular Band)

Test conditions: Unless otherwise noted, the following conditions apply to typical performance specification under static

-35 dBm (High-gain mode), LO/2 = Low, In case of activated LO/2 divider the current consumption increases by 2 mA. In a

cascaded configuration Gain and IP3 values are also influenced by the SAW filter. No correction has been made for filter

loss (1.6 dB) and interstage board trace losses.

No.
