HMC221B
APPLICATIONS INFORMATION
EVALUATION PRINTED CIRCUIT BOARD (PCB)
Generate the circuit board used in this application with proper
RF circuit design techniques. Signal lines at the RF port must
have 50 Ω impedance and connect the package ground leads
and package bottom directly to the ground plane similar to that
shown in Figure 14. The evaluation circuit board shown Figure 14
is available from Analog Devices, Inc., upon request.
Data Sheet
TYPICAL APPLICATION CIRCUIT
Two cascaded, CMOS inverters, biased with VDD = 5 V, can
generate complementary control voltages, VCTL = 0 V/5 V, for
the A and B inputs. Therefore, the HMC221B can be controlled
from a single CMOS input line (see Figure 15).
