In some embodiments, each of the frequency multipliers 1154-1, 1154-2, and 1154-n may be configured to increase the frequencies in the received RF signals by different amounts. For example, the frequency multipliers 1154-1, 1154-2, and 1154-n may increase the frequencies by a factor of two, three, and four respectively. As a specific example, RF signals received by antenna 1152 having a center frequency of 60 GHz may be provided to frequency multipliers 1154-1, 1154-2, and 1154-n, which may generate RF signals having center frequencies of 120 GHz, 180 GHz, and 240 GHz, respectively. In this example, transmit antenna 1160-1 would transmit RF signals having a center frequency of 120 GHz, transmit antenna 1160-2 would transmit RF signals having a center frequency of 180 GHz, and transmit antenna 1160-n would transmit RF signals having a center frequency of 240 GHz. Each of frequency multipliers 1154-1, 1154-2, . . . , 1154-n may be implemented in any suitable way described herein including, for example, as a series of frequency multipliers. In this way, a higher-order frequency multiplier (e.g., a 4× frequency multiplier) may be implemented a single frequency multiplier (e.g., a 4× multiplier) or as a series of lower-order frequency multipliers (e.g., two 2× multipliers).
