... AGC dwell time (see Table 1). The AGC has a hysteresis of approximately 4dB. With the AGC function, the RSSI dynamic range is increased, allowing the MAX7030 to reliably produce an ASK out- put for RF input levels up to 0dBm with a modulation depth of 18dB. AGC is not required and can be dis- abled (see Table 1) ...

... This says that AGC1 is set high and AGC0 and AGC2 are set low. A unique feature of the MAX7030 is the integrated image rejection of the mixer. This eliminates the need for a costly front-end SAW filter for many applications. ...

... Drive T/R high to put the device in transmit mode; drive T/R low to put the device in receive mode. Crystal Oscillator (XTAL) The XTAL oscillator in the MAX7030 is designed to pre- sent a capacitance of approximately 3pF between the XTAL1 and XTAL2 pins. In most cases, this corre- sponds to a 4.5pF load capacitance applied to the external crystal when typical PC board parasitics are added ...
