rakon Low cost SMD Temperature Compensated Crystal Oscillator for indoor wireless infrasture applications e.g femtocells The RFPT400 is a high stability SMD TCVCXO designed and specified specifically to meet the short-term stability requirements for indoor wireless infra-structure products, e.g femtocells. -jJ-H-duct description The RFPT400 is a high stability SMD TCVCXO designed and specified specifically to meet the short-term stability requirements for indoor wireless infra-structure products at a fraction of the cost of oven-stabilised oscillators. Using Rakon's advanced fourth-order analogue frequency compensation system 'Pluto™', the TCVCXO achieves unrivalled control of frequency variation with respect to temperature over the critical indoor temperature range. The stability of the RFPT400 allows a local area Base Station (BS) to achieve the frequency accuracy requirements of ETSI TS 125 104 without the need for minute-by-minute monitoring and adjustment. The BS's reliance on external sources of frequency compensation is reduced to an approximately once-per-week rate with a corresponding significant reduction in network load and infrastructure cost. Applications • Femtocell • Base stations 1.2 RoHS compliant Yes.
