GAIN (dB) LTC6433-15 Low Frequency to 1.4GHz 50 Gain Block IF Amplifier Fea T Descrip T n Low Frequency to 1.4GHz Bandwidth The LTC 6433-15 is a gain-block amplifier with excellent n 100kHz to 1GHz Flat Gain from a Single Demo Circuit linearity at frequencies below 100kHz to beyond 1000MHz n Low Frequency Cutoff Is User Defined and with low associated output noise. n 15.9dB Power Gain The unique combination of high linearity, low noise and n 52dBm OIP3 at 1MHz low power dissipation makes this an ideal candidate for n 47dBm OIP3 at 150MHz many signal-chain applications. The LTC6433-15 is easy n NF = 3.22dB at 150MHz to use, requiring a minimum of external components. It is n 1nV/Hz Total Input Noise Density at 150MHz internally input/output matched to 50 and it draws only n S11 < 10dB Up to 1.2GHz 95mA from a single 5V supply. n S22 < 10dB Up to 1.0GHz n The LTC6433-15 operates over a wide bandwidth. A single >2V Linear Output Swing P-P n demonstration circuit offers flat gain from 100kHz to 1GHz. P1dB =19.2dBm n DC Power = 475mW While this device is not capable of DC coupled operation, n 50 Single-Ended Operation users can define the low frequency cut-off by appropriate n Insensitive to V Variation CC choice of external components. n A-Grade 100% OIP3 Tested at 150MHz On-chip bias and temperature compensation maintain n Input/Output Internally Matched to 50 performance over environmental changes. n Single 5V Supply n Unconditionally Stable The LTC6433-15 uses a high performance SiGe BiCMOS process for excellent repeatability compared with similar a T GaAs amplifiers. All A-grade LTC6433-15 devices are tested n Single-Ended IF Amplifier and guaranteed for OIP3 at 150MHz. The LTC6433-15 is n ADC Driver housed in a 4mm 4mm 24-lead QFN package with an n CATV exposed pad for thermal management and low inductance. n Test Equipment L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
