description avago technologies iam-93516 is a high linearity gaas fet mixer using 0.5um enhancement mode phemt technology. this device houses in a 3x3 lpcc package. the iam-93516 has a built-in lo bufer amplifer and an if amplifcation stage that serve as an ideal solution for reducing board space and delivering excellent high iip3, gain and isolation with a low lo drive power. the device is designed with a diferential confguration to provide good noise immunity. the lo port is 50 ohm matched and can be driven difer - ential or single ended. an interstage match is introduced between the mixer and amplifer stage to allow device tuning at the desired rf and lo frequency. the interstage match can be a simple low pass, high pass or intermedi - ate frequency trap. the amplifer output port is 200 ohm matched and fully diferential. the simple matching at the rf port provides for optimum input return loss, noise fgure and iip3 performance. the iam-93516 is ideally suited for frequency down con - version for base station radio card receiver, microwave link receiver, mmds, modulation and demodulation for receiver and general purpose resistive fet mixer, which require high linearity. all devices are 100% rf and dc tested. features ? dc =5v @ 111ma (typ.) ? rf =1.91 ghz, pin rf = -10 dbm; ? lo =1.7 ghz, pin lo = 0 dbm; ? if = 210 mhz unless otherwise specifed ? high linearity: 23.1 dbm iip3(typ) ? conversion gain: 9.4 db typical ? low noise figure: 11.6 db ? wide band operation: ? 400-3000 mhz rf & lo input ? 70 C 300 mhz if output ? fully diferential or single ended operation ? high p1db: 19.3 db typical ? consistent rf performance over lo power ? low current consumption: 5v@ 111ma typical ? excellent uniformity in product specifcations ? 3mm x 3mm x 0.9mm lpcc package ? mttf > 300 years [1] ? msl-1 and lead-free. applications ? frequency down converter for base station radio card, microwave link transceiver, and mmds ? modulation and demodulation for receiver ? general purpose resistive fet mixer for other high linearity applications iam - 93516 high linearity integrated gaas mixer data sheet

notes: 5. distribution data sample size is 510 samples taken from 3 diferent wafers lots. future wafers allocated to this product may have nominal val - ues anywhere between the upper and lower limits. 6. measurements were made on a production test board, which represents a trade-of between optimal gain, iip3, nf, p1db and isolation. board losses of 0.1db at the rf input and if amplifer output have been compensated. balun loss of 0.57db which was obtained from the tokos sup - plied s-parameter fle is also compensated. the total if amplifer output loss is 0.67db. 7. the device current is measured without lo signal. at lo=0dbm, the current reduces by around 6 to 7ma. 8. gain, p1db, isolation and return loss test conditions: f rf =1.91ghz, f lo = 1.7ghz, f if = 210mhz, pin rf = -10dbm, pin lo = 0dbm. iip3 test condition: f rf1 = 1.91ghz, f rf2 = 1.89ghz, f lo = 1.7ghz, pin rf = -10dbm, pin lo = 0dbm. 3.0 iam-93516 electrical specifcations [6,8] t a = 25 o c, dc = 5v, rf freq = 1.91ghz, pin rf = -10dbm, lo freq = 1.7ghz, pin lo = 0dbm (unless otherwise specifed) 4.0 iam-93516 typical performance [9,10] t a = 25 o c, dc = 5v, rf freq = 1.91ghz, pin rf = -10dbm, lo freq = 1.7ghz (unless otherwise specifed) figure 4. iam-93516 demoboard schematic optimally tuned at f rf = 1.91ghz and f lo = 1.7ghz symbol parameter and test condition units min. typ max. id [7] device current ma 95.0 111.2 125.0 g c conversion gain db 7.9 9.4 10.9 iip3 [8] output third order intercept point dbm 20.5 23.1 - nf ssb noise figure db - 11.6 - p1db output power at 1db gain compression dbm - 19.3 - rl rf rf port return loss db - 12.0 - rl lo lo port return loss db - 20.0 - rl if if port return loss db - 11.0 - isol l-r lo-rf isolation db - 26.0 - isol l-i lo-if isolation db - 20.0 - isol r-l rf-if isolation db - 32.0 - rf 1.nh 1.pf .nh .nh 1.pf 1nh 0.pf nh 0nh 1pf ohm 1.pf 1nh 0.pf nh 0nh 1pf ohm interstage match interstage match if 1000pf 1000pf lo + lo - balun transformer toko bf 1db-101
