SA601 - Low voltage LNA and mixer - 1GHz

General 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.

Key Features

  • Low current consumption: 7.4mA nominal, 4.4mA with the mixer powered-down GND 8 LOIN1 9 LOIN2 10.
  • 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.

Philips Semiconductors RF Communications Products Product specification Low voltage LNA and mixer - 1GHz SA601 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.
