Gain controlled external low noise amplifier |
摘要 |
A receiver for receiving radio frequency signals from a remote keyless entry system and another system includes a low noise amplifier for amplifying and increasing the range and sensitivity of the receiver, such that the receiver may receive signals at increased distances. A gain of the low noise amplifier is selectively controlled to cycle from a first gain level that provides for increased sensitivity and a second gain level that provides a lower sensitivity and a greater dynamic range or larger signal capacity.
