It directly converts the satellite signals from the LNB to the baseband using a broadband I\/Q downconverter. The operating frequency range extends from 925MHz to 2175MHz.\u003c\/p\u003e \u003cp\u003eThe device includes an LNA and an RF variable-gain amplifier, I and Q downconverting mixers, and base-band lowpass filters and digitally controlled baseband variable-gain amplifiers. Together, the RF and base-band variable-gain amplifiers provide more than 80dB of gain control range.\u003c\/p\u003e \u003cp\u003eThe Maxim MAX2121 includes fully monolithic VCOs, and a complete fractional-N frequency synthesizer. Additionally, an on-chip crystal oscillator is provided along with a buffered output for driving additional tuners and demodulators. Synthesizer programming and device configuration are accomplished with a 2-wire serial interface.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e925MHz to 2175MHz frequency range\u003c\/li\u003e \u003cli\u003eMonolithic VCO \u003cul\u003e \u003cli\u003e-97dBc\/Hz at 10kHz low phase noise\u003c\/li\u003e \u003cli\u003eNo calibration required\u003c\/li\u003e \u003c\/ul\u003e\n\u003c\/li\u003e \u003cli\u003e-75dBm to 0dBm high dynamic range\u003c\/li\u003e \u003cli\u003e123.75MHz integrated LP filters\u003c\/li\u003e \u003cli\u003eSingle +3.3V �±5% supply\u003c\/li\u003e \u003cli\u003eLow-power standby mode\u003c\/li\u003e \u003cli\u003eAddress pin for multituner applications\u003c\/li\u003e \u003cli\u003eDifferential I\/Q interface\u003c\/li\u003e \u003cli\u003eI2C 2-wire serial interface\u003c\/li\u003e \u003cli\u003eVery small, 5mm x 5mm, 28-pin TQFN package\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003ca href=\"https:\/\/www.mouser.com\/datasheet\/2\/256\/MAX2121-1515792.pdf\"\u003eDatasheet\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e","brand":"sparkfun-10","offers":[{"title":"Default Title","offer_id":40054672261205,"sku":"19557:COM-19557:spark","price":2025.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/products\/19557-Maxim_Integrated_MAX2121_Direct-Conversion_Tuner_IC.jpg?v=1651340550","url":"https:\/\/www.tanotis.com\/products\/sparkfun-maxim-integrated-max2121-direct-conversion-tuner-ic","provider":"Tanotis","version":"1.0","type":"link"}
