HMC832

RF PROGRAMMABLE OUTPUT RETURN LOSS

The HMC832 features programmable RF output return loss

(VCO_REG 0x03[5]) and 12 dB of programmable gain

(VCO_REG 0x07[3:0]), as shown in Figure 26 and Figure 25.

Maximum output power is achieved with a high return loss

setting (VCO_REG 0x03[5] = 0), as shown in Figure 22. Setting

VCO_REG 0x03[5] = 1 improves return loss for applications

that require it at the cost of reduced RF output power (see

Figure 22).

MUTE MODE

The HMC832 features a configurable mute mode, along with the

ability to independently turn off outputs on both RF_N and

RF_P output pins. Figure 35 shows isolation measured at the

output when the mute mode is on (VCO_REG 0x03[8:7] = 3d),

and when the mute mode is off (VCO_REG 0x03[8:7] = 1d), with

either both outputs disabled (VCO_REG 0x03[3:2] = 0) or one

output enabled and the other disabled (VCO_REG 0x03[3:2] = 1d).
