LTE　femto　cell　is　very　popular　in　communication　fields.　The　size　and　the　cost　of　LTE　femto　BS　should　be　paid　more　attention.　Here,　we　designed　a　low　cost　MIMO　RF　transceiver　for　LTE　femto　base　station,　which　also　has　small　size.　After　the　analyses　of　the　transmitter　and　receiver　requirements,　we　put　forward　block　level　RF　parameters.　In　the　paper,　the　RF　transceiver　was　separated　into　many　sub-modules;　each　one　was　separately　designed　and　realized　successfully.　The　final　results　demonstrate　that　the　fully　integrated　RF　transceiver　not　only　has　small　size　but　also　met　the　requirements　of　LTE　femto　BS.　The　approach　of　design　and　implementation　could　be　pushed　into　the　commercial　use.
