Patent ID: 7741710

Claim:
A radio frequency (RF) amplifier module, comprising: a module substrate; a first active substrate mounted on the module substrate, the first active substrate comprising: a first transmitting amplifier configured to produce a first amplified RF signal in response to a first transmitting RF signal in a first frequency band; a second transmitting amplifier configured to produce a second amplified RF signal in response to a second transmitting RF signal in a second frequency band; a first reception amplifier configured to produce a third amplified RF signal in response to a first reception RF signal in the first frequency band; and a second reception amplifier configured to produce a fourth amplified RF signal in response to a second reception RF signal in the second frequency band; and a passive substrate mounted on the module substrate and in electronic connection with the first active substrate, the passive substrate comprising: a first diplexer configured to receive the first amplified RF signal from the first transmitting amplifier and the second amplified RF signal from the second transmitting amplifier, wherein the first diplexer is configured to send the first amplified RF signal and the second amplified RF signal to a first antenna; and a second diplexer configured to receive the first reception RF signal and the second reception RF signal from a second antenna, wherein the second diplexer is configured to send the first reception RF signal to the first reception amplifier and to send the second reception RF signal to the second reception amplifier.
