NXP SiGE:C LNAs BGU706x
Multi-stage integrated base station
LNAs with lowest NF
Delivering`multiple`stages`in`one`design,`these`SiGe:C`BiCMOS`LNAs`deliver`the`industry’s`lowest`
noise`figure`(0.66`-`1.05`dB)`for`the`receive`chain`in`silicon,`while`saving`up`to`80%`in`component`
cost.`Additionally,`the`analog`gain`control`up`to`35`dB,`the`RF`input`power`overdrive`of`10-15`dBm`
and`the`high`linearity`(0.7`-`0.9`dBm`IP3I`at`maximum`gain)`make`them`very`suitable`in`small`cell`
sizes`with`demanding`blocking`requirements.

``Wireless`point-to-point`and`repeaters
The`NXP`BGU706x`is`an`excellent`choice`for`modem`base`
station`receivers`in`the`wireless`communication`infrastructure,`
where`extreme`sensitivity`and`intermodulation`characteristics`
demand`sub-1`dB`noise`figures`and`high`linearity`for`the`low`
noise`amplifier`(LNA).`

(8`x`8`x`1.3`mm)
When`signals`arrive`at`the`base`station`receiver,`they’re`
typically`quite`weak.`For`this`reason,`the`received`signal`
is`often`fed,`just`after`the`duplexer,`to`an`LNA`for`direct`
amplification.`The`LNA`conditions`the`signal`and`then`sends`it`
over`the`long`cable`that`connects`the`top`of`the`base`station`to`
the`bottom.`When`the`signal`reaches`the`lower`cabinet,`further`
analog`and`digital`processing`is`performed.`If`the`LNA`needs`
to`handle`large`input`signals,`a`variable`RF`attenuator`function`
is`also`required.`The`extensive`feature`set`of`the`BGU706x`
makes`it`well`suited`to`meet`all`these`LNA`requirements.`
