Functional Description
The PMB2201 is a modulator and mixer circuit with high integration level. It includes a direct quadrature modulator and a double balanced Gilbert cell mixer with according bias circuitry.
The up/down conversion mixer combines two external signals at the RF and IF inputs. The IF input is suited for the lower frequency signal because of its linear transfer function to the mixer output. The higher frequency signal is fed to the RF input to switch the Gilbert cell mixer. In a typical application the wanted mixer output product is bandpass filtered and then fed to the modulator LO input. The mixer may also be used to convert the modulator output signal from E/EX via the IF/IFX input by mixing with a local oscillator signal RF/RFX to higher frequencies up to 2.5 GHz.
The modulator generates two orthogonal carriers which are mixed with the baseband modulation signals A and B in Gilbert multipliers. The outputs of the Gilbert cells are added and amplified by a linear output stage. The modulated signal is available at the open collector output E,EX. The voltage TREF can be used for DC biasing of the modulation inputs A, AX, B, BX externally.
The modulator and the mixer have separate power supplies and grounds. They can be powered down independently. Due to the power down concept the modulator can be used without or in conjunction with the up/down conversion mixer part.
For applications in the frequency range from 1.4GHz to 2.5GHz the derivative PMB2202
is offered.

DESCRIPTION
The NE/SA612A is a low-power VHF monolithic double-balanced mixer with on-board oscillator and voltage regulator. It is intended for low cost, low power communication systems with signal frequencies to 500MHz and local oscillator frequencies as high as 200MHz. The mixer is a “Gilbert cell” multiplier configuration which provides gain of 14dB or more at 45MHz.
The oscillator can be configured for a crystal, a tuned tank operation, or as a buffer for an external L.O. Noise figure at 45MHz is typically below 6dB and makes the device well suited for high performance cordless phone/cellular radio. The low power consumption makes the NE/SA612A excellent for battery operated equipment. Networking and other communications products can benefit from very low radiated energy levels within systems. The NE/SA612A is available in an 8-lead dual in-line plastic package and an 8-lead SO (surface mounted miniature package).

General Description
The HPMX-2007 vector modulator/mixer IC is designed to meet the needs of cellular and
PCS telephone applications. The heart of the IC is a vector (or quadrature) modulator followed
by a Gilbert cell mixer. The modulator and mixer can be used together, drawing only 25 mA from a 3.0 volt supply. The mixer can be disabled by connecting either LOmix or LOmix to VCC, allowing operation of the modulator alone and reducing current drain to only 10 mA.
The i and q signal inputs are balanced to insure high common mode noise rejection. The output of the mixer is a differential pair of open collectors. One collector can be connected to VCC and the other matched to 50 W using a shunt L, series C network. Alternatively, the output can be matched to 50 W through a 4:1 balun.
The SSOP-16 package insures that the IC occupies a minimal amount of printed circuit board space. The HPMX-2007 is manufactured using Hewlett-Packard’s 30 GHz ISOSAT-II process which combines stepper lithography, self alignment, ion implantation techniques and gold metallization to produce state-of-the-art RFICs.

General Description
The HMC400MS8 is a high dynamic range passive MMIC mixer in a plastic surface mount 8 lead Mini Small Outline Package (MSOP) covering 1.7 to 2.2 GHz. Excellent input IP3 performance of +36 dBm for down conversion and +29 dBm for up conversion is provided for 2.5G & 3G GSM/CDMA based UMTS or PCS applications at an LO drive of +17dBm. With a 1dB compression of +21 dBm, the RF port will accept a wide range of input signal levels. Conversion loss is 8.5dB typical and LO isolations are maintained at 22 to 33 dB. This miniature singleended monolithic GaAs FET mixer does not require any external components or bias. The 50 to 300 MHz IF frequency response will satisfy many UMTS/PCS transmit or receive frequency plans confi gured for low side LO. The HMC400MS8 input IP3 performance coupled with its high P1dB rivals traditional active FET mixers while offering a much smaller 14.8mm2 standard IC footprint and no DC bias.
