A positive voltage controlled 4 bit decoder is integrated on the switch. The switches may be used in either 75 ohm or 50 ohm systems. SWITCHES - MATRIX - SMT 12 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 functionality may be interchanged. The recommended loading 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.

The VL, VH, HL, and HH inputs of the first switch should be connected to the second switch, as illustrated. Mirror image switch performance can be realized by inverting the HV1 & HV2 logic control signals of one of the HMC276LP4 switches. The input loading impedance of two switches in parallel should be 31.25 ohms. The output loading impedance on each output should be 75 ohms. The interconnect RF line between the switch’s inputs should be an RF trace with a characteristic impedance of 62.5 ohms. This will allow the switch to remain matched in all possible switch states. Each HMC276LP4 requires DC blocking capacitors on ALL RF input and output ports. SWITCHES - MATRIX - SMT 12 The HMC276LP4 does not provide output to output (OP1 to OP2) isolation. For this reason, it is recommended that external amplifiers should be used at each output. The amplifier’s reverse isolation will provide output to output isolation, if this is necessary. 12 - 50 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com HMC276LP4 / 276LP4E v01.0409 GaAs MMIC 4x2 SWITCH MATRIX, 0.2 - 3.0 GHz Evaluation PCB The circuit board used in the final application should be generated with proper RF circuit design techniques. Signal lines at the RF port should have 50 ohm impedance and the package ground leads and exposed paddle should be connected directly to the ground plane similar to that shown above. A generous number of ground vias should be used to interconnect top/bottom ground planes. The evaluation circuit board shown above is available from Hittite Microwave Corporation upon request.
