9-; Rev ; /00 MAX0/////7 Evaluation Kits General Description The MAX0/MAX/MAX/MAX/MAX/ MAX7 evaluation kits (EV kits) simplify evaluation of these high-linearity, silicon germanium (SiGe), dualband LNAs/mixers. They enable testing of the devices RF performance and require no additional support circuitry. The signal inputs and outputs use connectors to simplify the connection of RF test equipment. The MAX0/////7 EV kits are assembled with an associated IC and incorporate input and output matching components optimized for the 89MHz to 89MHz cellular frequency band, 90MHz to 990MHz frequency band, 0MHz digital mixer output frequency, and 0MHz FM mixer output frequency. All matching components may be changed to work at other frequencies within the bands specified in the MAX0/////7 data sheet. PART TEMP.

MAX0/////7 Evaluation Kits ) Connect one RF signal generator to the LNAINL (LNAINH) connector for cellular () band testing. Do not turn on the generator s output. Set the generator for an output frequency of 88MHz (90MHz) for cellular () band operation. Set the power level to -dbm. ) Connect the spectrum analyzer to the LNAOUTL (LNAOUTH) connector for cellular () band. Set the center frequency to 88MHz (90MHz) for cellular () band, and span to MHz. ) Turn on the RF signal generator. The peak that appears on the spectrum analyzer should have a magnitude of about -dbm in high-gain and FM modes. In low-gain modes, the magnitude should be about -7dBm. Be sure to account for cable losses (between 0.dB and db) and circuit board losses (approximately 0.dB) when computing gain and noise figure. ) (Optional) Another method for determining gain is by using a network analyzer. This has the advantage of displaying gain over a swept frequency band, in addition to displaying input and output return loss. Refer to the network analyzer manufacturer s user manual for setup details. Table. MAX Mode Selection JU SHUNT * JU SHUNT Don t care *JU is connected to the MAX SHDN pin.

Keep traces carrying RF signals as short as possible to minimize radiation and insertion loss due to the PC board. Keep the differential mixer output traces together and of equal length to ensure signal amplitude balance. Solder the entire bottom side slug evenly to the board ground plane for best RF performance. Run the input trace to the LNA on the top layer of the PC board avoiding via-induced coupling. Minimize the parallel length of the cellular LNA input trace with the LNA input trace. 0
