Low-Noise Si Transistors up to 2.5 GHz
All these general purpose low-noise wideband amplifiers (LNAs) are based on Silicon Bipolar technology. Their moderate transition frequency fT of 20 GHz makes them easy to use and stabilize while offering a competitive price-performance ratio. Recommended for CA TV, Tuner, FM and ISM Band, the entire device series has suitable breakdown voltage to safely support a 5V supply voltage.
The stated gain values G max apply to a frequency of 900 MHz (products for low frequencies) respectively to 1800 MHz (products for high gain up to 2.5 GHz). The noise figure NF min has been measured in a test fixture with a noise match at the input; the listed values apply to low frequencies. All OIP3 and OP1dB values have been measured in the 50 Ohm system and can be optimized by choosing an appropriate load impedance.
