HMC344LC3 v02.1210 GaAs MMIC SP4T NON-REFLECTIVE SWITCH, DC - 8 GHz Features Broadband Performance: Dc - 8 Ghz integrated 2:4 ttl Decoder high isolation: 40 dB@ 6 Ghz low insertion loss: 2 dB@ 6 Ghz Non-reflective topology Typical Applications the hmc344lc3 is ideal for: • Broadband, Military, Radar & ECM • Fiber Optics • Switched Filter Banks • Wireless below 8 GHz • Test Instrumentation Functional Diagram General Description the hmc344lc3 is a broadband non-reflective GaAs meSFet SP4t switch in a ceramic 3x3 mm leadless surface mount package. covering Dc to 8 Ghz, this switch offers high isolation and low insertion loss. the hmc344lc3 includes an integrated binary decoder circuit which reduces the required logic control lines to two. the switch operates using a negative control voltage of 0/-5V, and requires a fixed bias of -5V. Simple external level shifting circuitry allows this switch to be controlled with most ttl/cmoS positive logic families. 15 SwitcheS - multi-throw - Smt Electrical Specifications, TA = +25° C, With 0/-5V Control, 50 Ohm System Parameter insertion loss Frequency Dc - 2.0 Ghz Dc - 6.0 Ghz Dc - 8.0 Ghz Dc - 2.0 Ghz Dc - 4.0 Ghz Dc - 6.0 Ghz Dc - 8.0 Ghz Dc - 2.0 Ghz Dc - 4.0 Ghz Dc - 6.0 Ghz Dc - 8.0 Ghz Dc - 8.0 Ghz 0.5 - 8.0 Ghz 0.5 - 8.0 Ghz 43 35 32 30 15 12 12 12 12 22 min. typ. 1.6 2.0 2.5 50 45 45 40 17 16 16 17 15 26 43 20 70 max. 2.0 2.8 3.0 units dB dB dB dB dB dB dB dB dB dB dB dB dBm dBm ns ns isolation return loss “on State” return loss input Power for 0.1 dB compression input third order intercept (two-tone input Power = +7 dBm each tone) Switching characteristics triSe, tFAll (10/90% rF) toN, toFF (50% ctl to 10/90% rF) “off State” Dc - 8.0 Ghz 15 - 1 For price, delivery and to place orders: Hittite Microwave Corporation, 20 Alpha Road, 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 HMC344LC3 v02.1210 GaAs MMIC SP4T NON-REFLECTIVE SWITCH, DC - 8 GHz Isolation 0 -10 ISOLATION (dB) -20 -30 -40 -50 -60 -70 RF1 RF2 RF3 RF4 Insertion Loss vs. Temperature 0 INSERTION LOSS (dB) -1 -2 -3 +25 C +85 C -40 C -4 -5 0 1 2 3 4 5 6 7 8 9 FREQUENCY (GHz) 0 1 2 3 4 5 6 7 8 9 10 FREQUENCY (GHz) Return Loss 0 RFC RF1,2,3,4 On RF1,2,3,4 Off 0.1 and 1 dB Input Compression Point 32 INPUT COMPRESSION POINT (dBm) 30 28 26 24 22 20 18 1.0 dB 0.1 dB -5 RETURN LOSS (dB) 15 SwitcheS - multi-throw - Smt 15 - 2 -10 -15 -20 -25 0 1 2 3 4 5 6 7 8 9 FREQUENCY (GHz) 2 3 4 5 6 7 8 9 FREQUENCY (GHz) Input Third Order Intercept Point iNPUT THIRD ORDER INTERCEPT (dBm) 49 47 45 43 41 39 37 35 0 1 2 3 4 5 6 7 8 9 FREQUENCY (GHz) RF1 RF2 RF3 RF4 Bias Voltage & Current Vee range = -5.0 Vdc ± 10% Vee (Vdc) -5.0 iee (typ.)
