SA621 - 1GHz - Low voltage LNA / mixer and VCO

Description

The SA621 is a combined low-noise amplifier, mixer and VCO designed for high-performance low-power communication systems from 800-1000MHz.

The low-noise preamplifier has a 1.7dB noise figure at 881MHz with 15dB gain and an IP3 intercept of -7dBm at the input.

Features

  • Low current consumption.
  • Outstanding gain and noise figure.
  • Excellent gain stability versus temperature and supply voltage.
  • LNA, mixer and VCO power down capability.
  • Monotonic VCO frequency vs control voltage SR01429 Figure 1. Pin Configuration.

INTEGRATED CIRCUITS SA621 1GHz - Low voltage LNA, mixer and VCO Product specification IC17 Data handbook 1997 Nov 07 Philips Semiconductors Philips Semiconductors Product specification 1GHz low voltage LNA, mixer and VCO SA621 DESCRIPTION The SA621 is a combined low-noise amplifier, mixer and VCO designed for high-performance low-power communication systems from 800-1000MHz. The low-noise preamplifier has a 1.7dB noise figure at 881MHz with 15dB gain and an IP3 intercept of -7dBm 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 12dB noise figure and IP3 of +4.5dBm at the input at 881MHz.
