Definitions
- the receiver must have a low noise figure (or "NF") and an adjustable power gain in order to adjust the signal's level at the input of the demodulator and to guarantee the broadest possible range of gain variation as appropriate for the terrain configuration.
- NF noise figure
- a low-NF, variable-gain amplifier is inserted into the reception sequence right after the antenna, cable, and filter.
- the noise from the amplifier must be low enough to add little noise to the reception chain, and the amplifier must exhibit a linearity and output power which are sufficient to enable the simultaneous amplification of high-level and low-level amplitude signals without distortion, throughout the entire range of the variation being considered.
- the option to adjust the amplifier's gain makes it possible to offset temperature variations within the reception sequence in order to maintain a roughly constant gain value.
- the object of the present invention is an integrated iow-noise-figure, variable-gain amplifier comprising a cascode amplification stage which comprises, connected serially, a low-voltage MOFSET transistor installed as a common source, followed by a bipolar high breakdown voltage transistor, with at least twice the voltage of the MOFSET transistor, installed as a common base.
- a resistor is placed between the bipolar transistor's collector and the grid of the cascode stage's MOSFET transistor, and the cascode stage is electrically powered through a choke.
- the cascode (a contraction of "cascade to cathode") stage operates like an amplification stage whose gain may vary continuously by several decibels. It is intended to ensure linearity and enable the smallest possible gain variations intervals, without degrading the noise figure. Increasing the linearity and power involves increasing the voltage and current deviation.
- the combined use of a low-voltage MOSFET transistor, approximately 3 V, about 3 V-3.3 V for example, and a bipolar high-breakdown voltage transistor leads to a very good amplifier linearity. This combination is achieved in a technology known as BiCMOS (Bipolar Complementary Metal-Oxide Semiconductor).
- the second VGA amplifier 106 with very-!ow-noise and variable-gain, has a gain of about 12 dB, a maximum noise figure of 5 dB, and an intermodulation product of about 3 at the input, which is greater than 25 dBm for an adjustment range of about 15-20 dB.
- increasing the gain of the first LNA amplifier 105 would require reducing the gain and increasing the consumption of the second amplifier 106 in order to maintain linearity.
- Second, reducing the gain of the first LNA amplifier 105 would make the noise figure of the second variable-gain VGA amplifier 106 very difficult to guarantee across the entire range of gain variation. There is a need for great accuracy in the gain variation interval (less than 0.1 dB, for example, or even less than 0.5 dB) in order to achieve a gain value of the receiver 103 that is as accurate and close as possible to the desired gain value.
