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

P1dB =19.2dBm
demonstration circuit offers flat gain from 100kHz to 1GHz. n
DC Power = 475mW
While this device is not capable of DC coupled operation, n 50Ω Single-Ended Operation users can define the low frequency cut-off by appropriate n Insensitive to VCC Variation choice of external components. n A-Grade 100% OIP3 Tested at 150MHz n Input/Output Internally Matched to 50Ω On-chip bias and temperature compensation maintain n Single 5V Supply performance over environmental changes. n Unconditionally Stable The LTC6433-15 uses a high performance SiGe BiCMOS process for excellent repeatability compared with similar
applicaTions
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.
