Miniature Sub-GHz LTCC Filter supports TI CC112x transceivers.
Press Release Summary:
Designed for sub-1 GHz wireless applications using Texas Instruments CC112x series low power transceivers, LFD21 LTCC (low temperature co-fired ceramic) SMT filter measures 2.00 x 1.25 x 0.7 mm. Model LFD21868MMF has nominal operating frequency centered on 891.50 MHz ± 23.50 MHz and accommodates up to 500 mW transmit power output. Insertion loss is typically better than 1.73 dB transmit and 2.67 dB receive, and antenna port matches to nominal impedance of 50 Ω.
Original Press Release:
Sub-GHz LTCC Filter from Murata Supports TI CC112x Transceiver Series
Hoofddorp, Netherlands: Murata today announced the LFD21 dual matching filter designed specifically for sub-1 GHz wireless applications using the CC112x series of low power transceivers from Texas Instruments.
Believed to be the world’s smallest filter available, measuring just 2.00 x 1.25 x 0.7 mm this miniature LTCC (low temperature co-fired ceramic) surface mounted filter takes up much less board space than a discrete design and has been approved by Texas Instruments for use with their CC112x transceivers. With such small dimensions the extremely compact filter frees up board space for additional features. The LFD21868MMF has a nominal operating frequency centered on 891.50 MHz +/- 23.50 MHz and can accommodate up to 500 mW transmit power output. This tiny space saving device ensures board space, BOM count and engineering effort is kept to a minimum. Compared with a traditional inductor and capacitor design, the filter module replaces more than 10 discrete components.
Insertion loss is typically better than 1.73 dB transmit and 2.67 dB receive. The antenna port matches to a nominal impedance of 50 Ohm.
