NE600

Philips Semiconductors Product specification 1GHz LNA and mixer NE/SA600 DESCRIPTION The NE/SA600 is a combined low noise amplifier (LNA) and mixer designed for high-performance low-power communication systems from 800-1200MHz. The low-noise preamplifier has a 2dB noise www.datasheet4u.com figure at 900MHz with 16dB gain and an IM3 intercept of -10dBm at the input. Input and output impedances are 50Ω and the gain is stabilized by on-chip compensation to vary less than ±0.5dB over the -40 to +85°C temperature range. The wide-dynamic-range mixer has a 14dB noise figure and IM3 intercept of +6dBm at the input at 900MHz. Mixer input impedance is 50Ω with an open-collector output. The chip incorporates an option so the LNA can be disabled and replaced by a through connection. The amplifier IM3 intercept increases to +26dBm in this mode; thus, large signals can be handled. The nominal current drawn from a single 5V supply is 13mA and 4.2mA in the LNA thru mode.
