TheMC13850-900HEVK features the MC13850, which is a cost-effective, high IP3 low-noise amplifier (LNA) with low noise figure. This device is designed for general purpose RF applications, yet has excellent high frequency gain and noise figure. An integrated bypass switch is included to preserve high input intercept performance. The input and output match are external to allow maximum design flexibility. The LNA has two selectable IP3 modes, a bypass mode and a standby mode
- Selectable IP3 mode allows running at the desired IP3 performance
- Bypass mode improves dynamic range in variable signal strength environments
- Integrated logic-controlled standby mode with current drain < 1 μA
- On-chip bias sets the bias point
- Bias stabilized for device and temperature variations
- Selectable IP3 mode allows for running at the desired IP3 performance for a receiver's linearity
- Bypass mode has return losses comparable to active mode for use in systems
- Bypass mode improves dynamic range in variable signal strength environments
- Integrated logic controlled standby mode with current drain less then 1μA
- Total supply current 5mA at 2.7V in low IP3 mode and 10mA in high IP3 mode. <1 μA in bypass mode
