Product 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.
