摘要：
The features of a 500 MHz to 6 GHz dual, ultra low noise, high IP3 amplifier are discussed. The device features a gain of 25 dB at 900 MHz and 21 dB at 1900 MHz with noise figures of 0.6 and 0.7 dB at the two frequencies, respectively. The device is intended for applications in the 900 to 2400 MHz frequency range and can also be used in a dual-band configuration where a single transistor is used for each frequency band. The amplifier also offers a high IP3, achieving 31.8 dBm at 900 MHz and 32.5 dBm at 1900 MHz. It is well suited for the CDQ0303-QS amplifiers including LNAs and oscillators operating in RF and microwave mode.
