3. TECHNICAL BRIEF

3.5.7 UMTS Rx RF filter (FL1001 : EFCH2140TDE1)

An RF filter is located between the UMTS LNA and mixer. Insertion loss is important, but not as critical

as losses before the LNA. The most important parameters of this component include:

■

Out-of-band rejection or attenuation levels, usually specified to meet these conditions:

■

Far out-of-band signals - ranging from DC up to the first band of particular concern and from the last

band of particular concern to beyond three times the highest passband frequency.

■

Tx-band leakage - the transmitter channel power, although attenuated by the duplexer, still presents

a cross-modulation threat in combination with Rx-band jammers. The RF filter must provide rejection

of this Tx-band leakage.

■

Other frequencies of particular concern . bands known to include other wireless transmitters that

may deliver significant power levels to the receiver input.
