wideband vcos - smt 1 HMC587LC4B v03.0514 wideband mmic vco w/ buffer amplifier, 5 - 10 ghz general description features functional diagram the HMC587LC4B is a wideband gaas ingap voltage controlled oscillator which incorporates the resonator, negative resistance device, and varactor diode. output power and phase noise performance are excellent over temperature due to the oscilla - tors monolithic construction. the vtune port accepts an analog tuning voltage from 0 to +18 volts. the HMC587LC4B vco operates from a single +5v supply, consumes only 55 ma of current, and is housed in a rohs compliant smt package. this wideband vco uniquely combines the attributes of ultra small size, low phase noise, low power consump - tion, and wide tuning range. wide tuning bandwidth pout: +5 dbm low ssb phase noise: -95 dbc/hz @100 khz no external resonator needed single positive supply: +5v @ 55 ma rohs compliant 4 x 4 mm smt package typical applications low noise wideband mmic vco for applications such as: ? industrial/medical equipment ? test & measurement equipment ? military radar, ew & ecm electrical specifcations, t a = +25 c, vcc = +5v parameter min. typ. max. units frequency range 5.0 - 10.0 ghz power output 0 5 dbm ssb phase noise @ 100 khz offset -95 dbc/hz ssb phase noise @ 10 khz offset -65 dbc/hz tune voltage (vtune) 0 18 v supply current (icc) (vcc = +5.0v) 40 75 ma tune port leakage current (vtune = +18v) 10 a output return loss 7 db 2nd harmonic -15 dbc pulling (into a 2.0:1 vswr) 4 mhz pp pushing @ vtune= +5v 15 mhz/v frequency drift rate 0.8 mhz/c for price, delivery and to place orders: hittite microwave corporation, 2 elizabeth drive, chelmsford, ma 01824 phone: 978-250-3343 fax: 978-250-3373 order on-line at www.hittite.com application support: phone: 978-250-3343 or apps@hittite.com information furn is hed by an al og devices is believed to be a cc urate and re lia bl e. however, no responsibility is assumed by an al og devices for its u se, no r for any infring emen ts of pat en ts or other rights of third parties that may result from its use. specifications subject to change without notice. no license is granted by implication or otherwise under any patent or patent rights of analog devices. trademarks and registered trademarks are the property of their respective owners. for price, delivery, and to place o rd ers: an al og devices, inc., one techn ol ogy way, p.o. box 9106, norwood, ma 02062-9106 phone: 781-329-4700 o rd er online at ww w.an alog .com app li cation sup po rt: p ho ne: 1-800-analog-d
