A positive voltage controlled 4 bit decoder is integrated on the switch. The switch may be used in either 75 ohm or 50 ohm systems. Both switch outputs (OP1 & OP2) can independently select any of the four inputs (HH, HL, VH, VL) or simultaneously select the same inputs. Note that the switch is bi-directional and input/output function- ality may be interchanged. The recommended load- ing impedance is 62.5 ohms on each input (HH, HL, VH, VL) and 75 ohms on each output (OP1 & OP2). All data presented was measured in a 50 ohm (input/output) system.

Characterization on the HMC276QS24 was done using 0603 size 330pF capacitors on all RF ports. A 0.01µF DC decoupling capacitor (0603 size) is recommended for the Vdd pin. 14 - 154 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 12 Elizabeth Drive, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order Online at www.hittite.com 5 Page
