General Description
The HMC258LC3B is a 14.5 - 19.5 GHz surface mount
sub-harmonically pumped (x2) MMIC mixer with an
integrated LO amplifier in a SMT leadless ceramic
package. At 45 dB the 2LO to RF isolation eliminates
the need for additional filtering. The LO amplifier is a
single bias (+5V) two stage design with only 0 dBm
driver requirement. The HMC258LC3B requires
no external matching components, making it ideal
for integrated subsystem applications. Utilizing the
HMC258LC3B eliminates the need for wirebonding,
thereby providing a consistent connection interface
for the customer.
