Product Overview
The MAX2751EUA+ is a monolithic voltage controlled oscillator (VCO) in 8 pin µMAX package. This self contained VCO combines fully integrated oscillator and output buffer. The inductor and varactor elements of tank are integrated on-chip which greatly simplifies application of the device. The only required external components are couple of supply bypass capacitors. The IC provides direct connection to VCO tuning voltage input and VCO buffer output. The tuning voltage input range is 0.4V to 2.4V and oscillator frequency tuning range is factory adjusted to provide limits. The output signal is buffered by an amplifier stage (internally matched to 50 ohm) to provide higher output power and isolate the device from load impedance variations. Internal regulation of oscillator supply voltage eliminates need for an external LDO regulator for VCO. The MAX2751 is used in 802.11b DSSS WLAN, 802.11 FHSS WLAN, Home RF, 2.4GHz and Bluetooth ISM proprietary radio.
- Supply voltage range is 2.7V to 5.5V
- Operating temperature range from -40°C to 85°C
- SiGe monolithic VCO replaces modules in 2.4GHz ISM applications
- Frequency tuning range from 2120MHz to 2260MHz (240MHz to 280MHz IF)
- Internally matched output buffer amplifier and on-chip tank circuit
- Output power of -3dBm, return loss of 12dB and harmonics of -30dBc
- Low current shutdown mode, shutdown supply current of 0.2μA
- Supply current of 9.7mA at TA = +25°C
- Phase noise of -125dBc/Hz (fOFFSET = 4MHz) and -151dBm/Hz (noise floor)
- Tuning gain of 175MHz/V (fOSC = 2400MHz, +3V) and 110MHz/V (fOSC = 2500MHz, +3V)
