The NE5209 is a wideband variable gain amplifier that combines high-speed bipolar process with the Gilbert architecture. It features single DC voltage control for gain, operates on a single 5V power supply, and consumes only 40mA. The amplifier has high impedance differential inputs and 50Ω differential outputs, allowing for AGC, impedance transformation, and balun functions.
The Philips NE/SA209 is a monolithic broadband RF amplifier designed with a high-speed bipolar process and Gilbert architecture. It features a single DC voltage-controlled gain, operating from a 5V supply with differential inputs and outputs suitable for impedance transformation and balun functions.
Key specifications include an 850MHz bandwidth, a maximum differential gain of 26dB, and a minimum noise figure of 7dB. The device supports a wide gain control range of over 60dB at 200MHz with exceptional linearity between the control voltage and gain.
