MAX2130 19-1806 Rev 1 8/03 Broadband, Two-Output, Low-Noise Amplifier for TV Tuner Applications General Description Features The MAX2130 broadband, low-distortion, low-noise, +5V Single-Supply Operation two-output amplifier performs preamp, loop-out, and 44MHz to 878MHz Operating Frequency Range buffer functions in TV tuner applications. The device integrates functions typically achieved with discrete Guaranteed 7.4dB (min) Input Return Loss Over components into the space-saving 8-pin MAX-EP Frequency Range package. The MAX2130 provides a gain of +15dB with LNA Performance at I = 93mA (R = 15k) a noise figure less than 3.2dB over the 44MHz to CC BIAS 878MHz frequency range. The MAX2130 features an 15dB Gain externally adjustable bias control, set with a single 2.8dB Noise Figure resistor, that allows the user to meet minimum linearity +17.5dBm Input IP3 requirements while reducing current consumption. The +27dBm Input IP2 device operates from a +5V single supply and only +2.7dBm Input 1dB Compression Point requires 93mA of supply current when nominally Loop-Out Amplifier Performance at I = 93mA CC biased.
