DESCRIPTION
The SA601 is a combined RF amplifier and mixer designed for
high-performance low-power communication systems from
800-1200MHz. The low-noise preamplifier has a 1.6dB noise figure
at 900MHz with 11.5dB gain and an IP3 intercept of -2dBm at the
input. The gain is stabilized by on-chip compensation to vary less
than ±0.2dB over -40 to +85°C temperature range. The
wide-dynamic-range mixer has a 9.5dB noise figure and IP3 of
–2dBm at the input at 900MHz. The nominal current drawn from a
single 3V supply is 7.4mA. The Mixer can be powered down to
further reduce the supply current to 4.4mA.
FEATURES
• Low current consumption: 7.4mA nominal, 4.4mA with the mixer
powered-down
• Outstanding LNA noise figure: 1.6dB at 900MHz
• High system power gain: 18dB (LNA + Mixer) at 900MHz
• Excellent gain stability versus temperature and supply voltage
• External >-7dBm LO can be used to drive the mixer
