Size estimate
The example layout below provides an effective size estimate for the RF front end. The total PCB measures 5 x 2 in (127 x 50.8 mm). Information regarding the size requirements of the different channels or circuits is highlighted below:
Rx ch = 4.00 sq. in
Tx ch = 3.53 sq. in
Digitizer + clk = 4.00 sq. in
RF PSN = 0.88 sq. in
Digitizer PSN = 2.56 sq. in
Fixed LO = 1.13 sq. in
Tunable LO = 3.90 sq. in
